About This Class

This class is about learning Robot Structural Analysis by designing a full project in a minimum time, from drawing a 3D model to making a seismic analysis.

Class level:


No previous Robot Software knowledge is required, but basic engineering and understanding of the design codes will be a plus.

Why you should take this class:

This class is very practical for real applications in engineering and will add value to your work in the Design field. Being a Structural Design Engineer myself, I use structural software daily, which allows me to use a minimum time for the design and analysis. 

What you'll learn: 

  • Draw different reinforced concrete elements to make a structure.
  • Static analysis and design of the structure.
  • Seismic analysis and design of the structure.
  • Design of different structural elements (columns, walls, slabs and foundation) using obtained loads.

What you'll create:

After this class you'll be able to:

  • Create a 3D Model of a given structure.
  • Design the whole structure and the different elements it contains based on load results.

Who am I?

My name is Marc Al Ghazal and I'm a Structural Design and Site Civil Engineer. I mostly work in the Structural Design and Analysis field and always enjoy learning new skills and techniques that would help me improve myself. By sharing my knowledge I hope to help fellow Engineers in their work fields.

How can we get in touch?

1. Introduction: Hello, everyone. My name is Mark and today we are going to learn off robots. Structural analysis Professional. First of all, you are going to start with a short introduction about this after it provides structural engineers with advanced simulation analysis and design for different types off structures. These structures can be residential buildings, more stadiums, etcetera. They can be off any material likely enforced from creates steel and wood. In this course, we're going to design a reinforced concrete residential building. So at the beginning, who are going to talk about the general life off a project we have, of course, the architectural drawings made by the architect. After that, the structural engineer will rely on these drawings to make structural analysis and design . After the space, we are going to have the structure of execution drawings on them. It be execution drawings made by engineers over draft persons andan the end the construction words. So in the scores who are going to do this part? The structural analysis on design We will begin by creating a project setting its references. After that will define different elements like columns, war slabs. We will drove the whole structure apply started clothes and see is make loads we can. After that begin this is make analysis. Toe at the end designed the columns, sheer worlds, slabs and foundations. So up next we are going to create a project and said it's references. 2. Project Preferences: Hello again, guys. Now we have opened robots Structural analysis, professional. In this window, we have open project on your project. If you click on more here will obtain different structure types like building design frame three D design shell design. So the main difference between these types is the number off coordinates like here and the frame to the design. We have only took ordinance ex and why it is not entreaty. We are more concerned about building design and shall design. They are the same thing and they have the same characteristics. So I'm gonna choose shall desire. Now we can start our new project. We should set the job references. We can find them in the bottom right corner. Or we can click on tools on Dhere Drop references. So for the units and four months I'm going to choose metric Yes and said my dimensions forces. It said that up. I like to work with John on for the moment. I'm meeting okay for the other. We have displacement temperature on the unit addition. Now, when the materials section I'm going to choose American on modification. We have steel, concrete, a lemon on December and other okay for the steal. We can choose here the steel material we want or we come in. Put it, man. Really? I'm going to stick with 242 m. P a as a resistance. As for the concrete, I'm going to start a new material. I'm going to name it C 25 US and concrete 25. I'm going to set the resistance toe 25 m p. A. The possible issue to 0.2. Now, as for the young model is and the sheer modernists, these are the equations or young, motherless and she and modernise. As you can see, young modernists is related Toe f prime C on the sheer model is is related toe the young motherless on the person operation No, for our 25 mpg resistance. We shouldn't put here this value for young mothers and this value for she and modernise. Then we click at on okay and we can choose it here in the drop down menu. We're not going to focus on the aluminum or timber because they are not in our structuralism. No, For the database we have the different goals used for steel and timber vehicle lows building swords, etcetera For very enforcing bars. We have the A C I 2000 and eight metric. We're going to leave it like that now for design codes we have for the RC structures The A C I on There's your technical a c I. And if you click on loads here, we can show the court combinations also based on a C i the snow wind loads on the A S C seven on the seismic loads on BBC 2000 and 12. We have also order versions for the ABC and we can choose here more goals Click on any quote we want on added here. OK, we can choose it. Also, I am not going toe change the parameters for the structure Analysis is on the model analysis. I'm goingto leave them by default for the world parameters, we can save the results and external file. And now for the machine we have two options for to have the iterative adjustment off the finite element, which mainly is a method toe, make the match coherent between structural elements like slabs on words, slabs and columns. First labs between them on the edge off these slabs. This option here will adjust finite element. Nash. As for the second option, they can omit the constraints and encouraging parents. I'm not going to check it. I'm going to talk about the shorty. This method assumes that the measures for the particular panel's like wars or slabs will not undergo adjustment. So the notes in thes slabs are united by means off economic, the constants. Like I said, I'm going to leave it blank, Uh, save my current parameters as default on Click Here are Okay, so now we are finished with the job references. Next, you are going to define structural elements. My columns, she rules slabs and beams. 3. Defining Elements: OK, guys. Now we can begin defining structural elements so we can find them here in geometry. Or we can click this. I can hear we went began with the columns or C column. We click here. Okay. For the dimensions we have B and H Keep in mind that H is for the X direction on B s for the Y direction. I will choose here 30 and here, 80 centimeters now for the reduction off moment off in a Shia. Why did use the moment off inertia where after the model is off, rupture is reached. The structural element cracks on the moment of inertia is reduced. So we as structural design engineers, we should take this into consideration. So we should reduce the moment off in ASHA and all our structural elements depending on these value was given by the A. C. I. We have different values for beams, columns, walls and slabs. So now I'm going to input 0.7 because it is a column on you can see here the material is C 25 Earth on clothes. Now it is the same procedure for the beams are see beam. Here we have be for the widths on H For the height, three will choose birthday and 50 and the reduction is 0.35 material. See 25 on and close. As for the floor, we have here different options. We will choose Shell because if you choose Curtin World, we wouldn't be able to generate final element match late social. It is. Ah So let's love I'm going to call it That's s 25 us and thickness. 25 centimeters on The reduction is 0.25 and you will click here toe change the material. See 25 at and clothes No, for the bulls, we have initial and robots the moment off Inertia for wards is for out off the plane banding rubber gun and change here. Now we know that the main function off a sheer role is to resist lateral forces given by their sees me close. So what is the solution? We will apply a concrete material with reduced eat with the world so we'll clean p 80 new material on the new young models will be syrup on seven times the old young mothers. Now to create a new material, we will go toe job references. Empathy is modification. We begin with C 25 on right here W C 25 ws in walls Now the new young motherless Who is going to be this value on off course you are goingto change. The sheer model is tow this value on and OK, that is OK now for the world's will create a new section We will call it w 30 thickness 30 centimeters. We will keep it one for the reduction off the moment off inertia. But we will change the material for C 25 w and Andi close this Now we have defined or the structural elements and our project. Next we are going toe begin throwing the structure on generate finite element much. 4. Drawing the Structure: and this. Listen, we are going to be entering our structure. We can import another cut file from here are we can choose the first I can here access definition. So the X window, the access are in the right direction but their distance is and the X direction. I'm going to choose three repetitions and four meters at and for their I the repetitions and three meters changed the numbering to ABC at apply close. If we stand in the top few on the X and why when so we can see clearly our spirit So we can begin to draw our structure for the color high three meters upper direction On the beginning. You we can see now the column. If you click here on section shapes, we are going to see only a line. So we're going to leave it like bet. Now we can do the same procedure for other columns or can click on edit. Both copy, copy. Pity the petitions on to select the translation vector. We are going to do the same And why direction or so period of petitions and respected. Okay, so now I'm going to delete these columns because I want to draw goals. So now, for the world's, like three upward direction and drag the beginning. Okay. Now for the beans, we should divine cam on the nose on. Finally, for this tub that says 25 shell. You are connecting the nose. Okay, guys. So I'm going to throw this second slab. We will assume this lab stairs normally, if we wanted to design this lab would leave this area blank. But here, in the structural design, off the whole structure they're stairs weight are important. So I'm going to drove them as a slap. You can make another definition or is there slab? But for now, I'm going to leave it like that. Now we can begin to generate the ministry. We can click on this item on matching options. Do you want to perform these operations for all parents? Yes. So it will select the walls on slabs. 11 size one meters. We can do it for less advanced options. Three. No triangle is okay. Now to generate to a click on this, we can see that the walls and slabs now has mash. Andi diminish is adjusted on the edges. Now we will stand in the front of you and select the bottom knows only to put our supports . We can click here fixed or bend when choose fix, apply close. We have supports on our bottom notes. I chose it supports because I wanted my foundations to will assist moments. I want my whole structure to transfer its moment toe my foundations Now I will click population to see if there are any others. So we have no others and no warnings. You can continue now. I was still like all this structure before he supports on Didn't copy five repetitions on the vector 003 Execute Yes knows now we have our six story building. So will you input some story information and J Almaty stories Stories. We will find them manually. Base 11 0 number off repetition six on high, three meters at on deploy. Now we can see that the stories are defined. So that's it for this structure and growing how to add it elements in our structure. We used rectangular shapes for the Collins and for the beans. But we can use other shapes here. We can see that we have a lot of different shapes to use even circular shapes on for the government angle. Here we can rotate the column both the beam, but I would do it later. As for this love, we used a homogeneous which is ascended to ways slap we can use in Ortho Tropic Slab, which we can set the main direction. No, you can set the time we have slam Hello, slab etcetera. So in our case, we use the two ways. So let's slow. I'm going to show you how we can rotate column or a bean. So we selected on we choose here. They're gonna anger f resected toe 90 degrees. We will rotate the column in the way that indicated to its original and protection so we can do the same for the team. Now I'm going to show you how toe draw an opening and a slab. First off, all, I'm going to drop a note. So geometry nodes. I'm going to place it here on clothes. So we're going to select an old on didn't Onda. We are going toe move it and the vector off one minus swan on zero. It's a cute So we have now our note here. I'm going to do the same for the other three. Niles toe, make a square. Now we have our four knows. We are going to click on Paulina and Contour. Andi, we're going to dro on the notes. So as you can see, we have now our opening and the slab. We can do the same procedure if we wanted to throw an opening in a world. So, guys, this is it for editing elements. Next we are going toe and put some static loads on defied load cases and combinations. 5. Applying Static Loads: Okay, guys, in this lesson, I'm going to show you help toe input static close on your structure. We have here loads, load types or we can click on this. I can hear no tax. So before beginning, I will talk briefly about load cases. We have self rate superimposed that load which usually means the tiling. Andi, the petition. We have the live low temperature effect on the earthquake loads. In this lesson, I'm going to input the self A STL and the live load only. In the next lesson, I will input the earthquake loads. I will show you briefly how to put temperature effect. But I will not use it in my project that are remote load cases like the wind. But in this project you will stick with the Earth Grey clothes on Lee. In general cases, the seismic effect is more important than wind loads, especially for six story buildings. Of course, there are exceptions and when those usually are calculated for clothing design now back to it. Oh, but we can see that there is a case here which is their self weight. It is automatically taken by robots so we don't need toe on, Put it again. We will only change the name, toe self weight on the label toe cell fate and click multiform now for their STL number two . That's the nature, of course that and we can see it here now for the live load nature lives and that so close we can see here that we have three new cases. We will go to low definition loads, low definition, or we can click on this. Aiken, we do not need toe put a low definition for the self rate. So we will begin with the super imposed. That load, surface and uniform planner note it will input the value off minus 0.5 don't per meter square. The minus is because it is in the downward direction and and now we are going toe select All this loves bar selection. We were select family and you can see the solar slept 25. So all our slabs are selected on only our slabs close. We can see them here so we will copy them and paste them and it looks now. If you want to see the loads, you can click on here load symbols. We can see the load symbols and loads value description so we can see the value or the STL load here. If you click on self weight, we can see that this labs, all the elements are highlighted now for the life load. We don't have any love, live loads that So we are going to define them. No definition surface. Well, in put a very off zero point toe us this residential building and and you were selected slabs and apply. So now we have the STL and the lifeboat. I have an important note. Usually it's level contain different areas like balconies and stairs. So the loads will have different values in each part at the stone by throwing different slabs for each part, like I did here with the stairs and then put the loads for each one. Now for the static load combinations, we have these combinations according toe, the A S C for strength design and for global stress design. These are the combinations that we're going to use, and this letter loads manual combinations. I'm gonna call it on the Enron pls on and one point for that look. Okay, so sulfate. And as the one points for apply? No, The 2nd 1 You 1.2 That load plus 1.6 life. Okay, The self great. And just er will have. Want reform to on the lives 1.6 Apply now for the last one. We call it 201 s s. That must live. Okay? And we have effected a fun. That's like So, guys, these are our static. Hello, combinations. I will show you briefly held to input temperature effect we have here low definition off course. After defining allowed case for the temperature, we could click on bar and we have here serving note we can and put it on bars or we can put it on surfaces. So, guys, for the next lesson, we will do the same but with Seznec notes. 6. Defining Seismic Cases: in this lesson, we are going toe define say it's make loads on base, make loads combinations. So we're going to click on analysis And as these types on the new well true say SMIC equivalent lateral bores method and OK, we will obtain this window saves make an SS parameters. Now I am not going to go into details for the seismic parameters. They are provided by the S E seven and the chapters 11 and well, or say something design for their fundamental period. I will use other structures for the direction that's and boy for the site class, I will choose Cyclist E unless it is not that otherwise in a geo technical report. As for these three parameters, they differ from a country to another. So I will input these values for them now for the response modification coefficient it has shown in the table 12 point toe in the A S. C. On it is connected to the building system. So in our case, it has a valuable for. And finally, the imports inspector is one for a residential building now. Okay, on Okay. To a New cases are now defined in the X and wind direction. They are static. CS make cases. Now we are going toe Click on go to mass conversion and we will select which mass will make the vibration. Nothing that the self it is taken by default will click here. That's the end close. We will leave the coefficient one on that and no life load. Close coefficient 0.25 as in 25%. And at so now we can close this window. After that, you are going toe klik calculations so we don't have any errors or warnings now to see their static based here results Any actions? David will be opened. We will choose here. There. Direction X in the ABC we will go down to the end. This is the value off our static base here y 94.7 on in their Y direction. We will have the same value. Now I'm going to calculate the dynamic salesman cases. So analysis analysis starts you and model with automatic definition off paceman cases. Okay. No, I want to select X plus minus y plus And why minus? Because it is important to use accidental eccentricities and dynamics. Ace mix According toe the Chapter 12 off the A C. We will take it as 5% off the dimension off the structure and perpendicular to the direction off the applied forces. So relative values 5% and simplified approach model analysis parameters we even begin with then moments for now on unchecked the Z direction for the active minister Elections Well done here Now, for the states make analysts parameters again. We can input our previous values that we used to calculate the static base here. City is also in the table 12.2 in the A s C Now for the base year are going toe input our static base year 1 94.7 We can also put a value off 85% off this value. It is a low by the coat. Okay, the erection definition. We're going to reduce the time off calculation by they can see it over here. But if you have, for example, a column implanted in a being, we must take the equal to one. No. Okay. Okay. And OK. And calculations. No. OK, guys, Now we have static and dynamic say Smith cases. Next we are going toe input. Our sales may close combinations 7. Defining Seismic Combinations: now guys were going toe. Would there say it's make load combinations and our modern? But before that, as you can see, I've changed the numbers off These days make cases to begin with 100 and one just to separate the different cases we mentioned earlier there load combinations that we are coming to use for the safe swimming design. These are the combinations for the strengths design and for the global stress design. According to the A S C seven Chapter 12 Section 4.2, we have different values for E according to the number of combinations. So we have a church class TV or H minus TV. Very ages effect off presenters. These make forces defined in this section equal toe this formula where below is the redundancy factor, and in our case we have assessment design category off the so we have the value off 1.3. So the age in our case is 1.3 times Q B as fun TV. It also differs according toe the combination. So for the combination 57 we have these values six and eight These values where the is that that load now? If we replace to the values obtained by the TV and th calculations, and our previous combinations will obtain for the strength designed. These combinations on global stress design these combinations. So now we can begin to input the combinations taking into account that you see it's create X in the X direction and A Y and the Y direction. Now we're going to begin the low combinations for the seismic cases. Minimal combinations. You We'll be going with 401 on and accidental. The first equation is the number 51.37 d plus one plus 1.3. It's great, can omitted. I will write it here. Okay, Now we can begin to input the cases. One for light loads. As for the Q E, we have eight different cases according to the direction off the suspect forces. So here we have e x x minus. We will choose this case and 1.3 at and new 402 accident id. Same procedure with that and live loads. But now, E. Why X minus Andi. Okay, there's the same combination, but with a different direction. For this is Mick forces. So now I'm going to choose 305 on 1.3 on deploy. As you can see, we have from 306 to 311. So we have six more combinations for only the number five and totally have 24 manual combinations to introduce the robot. I know there's a lot of combinations, but it is a very effective way to do their salesmen design. We can see the list off the combinations here and now I'm going to introduce all the combinations to Robot. These are there, or combinations is our for the equation for you. These for decoration Seven bees For the question six on these board aggression. Eight. We cannot this that immigration six and eight on SLS because they are for the global stress design. So now we are finished with the combinations. We can see them here In our next lesson, we are going to begin their say sneak analysts is on design 8. Seismic Analysis for the Whole Structure: everyone will come back in this lesson. We are going to check the results for the whole structure on. Verify that we can begin designing our elements. So first of phone, After calculating our structure, we are going to verify the model analysis. According to the S E, the analysis should include a sufficient number off modes to obtain a combined model mass participation off at least 90% off the mass off the structure and both X and y directions. Now, if you remember, we began with 10 months. So if the mass participation ratio is below 90% in our structure, we should increase the number off modes and start again results model, analysis. Now we are going to check the model cases. We will click on model Andi. The stable will be shown so we can check the period here 0.2 seconds, which is very good for building like ours on for the mass participation ratios and there X and Y directions. We have a total off 93 95% so it is acceptable. We are finished with the first verification. Now we are going to verify if the dynamic based year is equal to the static base year that we input earlier. Now results, reactions. We're going to choose the first say, Smith case on combination security. Check these two values 147 and 126. We can clearly see that the result is equal to the static base here that we ate the program . We can check it four or the dynamics A Smith Cases. It will give us the same result. So we checked the scaling and the model analysis on now are going to check their story drifts. We will click on results on a study table displacements and the first dynamics A's me case . So according to the S E, we have this equation over the story drift. You can see that we have city on the importance factor. In our case, you have city equal to four and importance factor equal to one. So we a pain. This equation now according to the table 12 on 12-1 there a global story left is equal toe 0.2 times h age being the height off. Her story on the value 0.0 toe is related to the important Spector and the type off our structure. No, they are you is the value given by robot for their story drift. So if we divide this value by H in a given story, we will obtain the story drift and guess what it is written by the U X or Y, depending on the direction. So this is the value that we are going toe check on. All we have to do is check if this value is smaller than 0.2 Now that two robot we have the u X and the Y according to direction. We can clearly see that the values are of course, they are not zero, but they are smaller than 0.2 If we wanted to make our own calculations, we could divide the audio exhorting Are you? Why? By 300 centimeters which is our story height. So we are going to check these two values for all our dynamic season cases. Andi to see if they are all smaller than 0.2 so we can see they are all small er's and 0.2 So, guys, we checked the scaling the model analysis on the story drift. Next we can begin our columns design 9. Columns Design: now, guys, we're going to begin the final part off our course, which is the design off the structure and elements. And in this lesson, we are going to design the Collins. First of all, I'm going toe klik display favorites toe unchecked the structural exes, which gives us a better view. Now I'm going to select a column from bottom to top and had it and a new window here. So we have all cut up in a new window. Now we can see here says I can local system. If the check it or click on it, we will have a local system for our bars. You can clearly see that the local system is different then the global system. We have the X direction here similar to the Z direction here. No, let's see the forces that act on these columns results diagram for bars. So these forces here, uh, in accordance with the local access. So the F X here is the compression or the tension force in the column. And the FBI and FC are the sheer forces. If you click on FX and that's why I'm going toe turn off the local axes, we can see a diagram forming here, So we are going to click on Labours to show the values apply. Now we are seen F X values in the bottom and top off every column. These values are for their self rate on Lee, so we can choose any combination. We want our case and we can see the values for each one. You can, uh, also choose combinations here which gives a Langella off. Although combinations, I'm going to select the columns again on a copy. Them here results or, says Andi, I will place him in the bars here, inventive to see the results only for the part number now in choose the combinations and select all the combinations to only see the load combinations for our columns. Now we have the results for every forces in every combination. For this specific color, we can silicone and copy them began based them and excel so we can take a better look at them there or use them and another software. Now I am going to begin the reinforcement off color. We click it on geometry, RC Design on and R C members required the enforcement I'm going to choose all the problems and open them in a new window? No. We will click on RC member calculation parameters to set our parameters. I will delete this one and start from sketch. So definition off a new calculation parameter set. We will call it columns. Seismic risk medium. You can set it to hurry. It depends on the area. Longitudinal reinforcement. The steel grade is for 20 m. P a. Clear cover you on and I'm gonna choose four points. Five Here. Okay, I'm gonna leave it 3.8 now. Transfer. So the enforcement good. Aid 300 and save. Yes, Close. Now we have our columns again. I'm going to choose columns and coffee done here on apply. So we applied these parameters for our our colors. Okay, so in this window, members, we only want the columns close. We have all our condoms here in the code combinations. You are going to set the ultimate limit, state. We are going to choose combinations and shows our ultimate combinations clothes on. And we are going to choose just less combinations on close. So we set our members and called combinations. We click on calculate. So now we are going toe check required the enforcement for the columns and percentage off the steal required. So the calculations are over. We do not have any warnings or others. Close. Now we have the stable. We kick on columns and we can see the results for our columns. So what? I've clinic David columns required reinforcement ratio and what stood up spacing on. And OK, we can see here the the enforcement ratio for all columns. If we click on a column, it will be highlighted here in this window. So you know which column it is, and you can see the percentage for each one. So here you can choose whatever you want to see in the stable. So, guys, now we have learned how to design columns in robot. Next, we are going to learn how to design words. 10. Walls Design: in this lesson. We are going to design holes, so I'm going to select a woman from bottom to top and open it in a new window. I'm going to disable panache to have a better view now. Results, maps, automatic direction If vision we are going to define our local direction. X the wars as the global Z axis. So we will have X in this direction. And why in the horizontal direction on. Okay, now we can select the moment to see in the x X. Why? Why? Or X y directions fly. You can see the maps. We can set the values on with finite element mash so we can see the moments, the stresses, the shear stresses or forces. And of course, we can, said the low combination that we want. We are going to begin their reinforcement for the world's So RC design slash required the enforcement There we are going to select the walls w 30 on and you and another window. No, we will click on plate and Shelley reinforcement part on. We are going toe begin from scratch. We will call it towards for the walls. Very enforcement calculations Start is of course bending and compression Tension on the Mary enforcement by actions is along a global Z access now materials grade for 20 and reinforcement. We are going to set over bar dimensions to 16 on and our cover to three centimeters. Of course, we can choose whatever bird type or bar dimension we want later and and close now we are going toe. Apply these parameters for what? Words close. Copy on. We will face them here. Lie close Now we are going toe Select our colonels pastes them here Waas close and will choose for the U. S. The 1st 2 combinations for s and s the combination. 201 on the combinations 501 to 516. And for the accident, we are going to choose our saves me combinations implored 100 to 416. Let me make a small green work for the column designed, abused. Earlier we put all our the ultimate combinations here. We didn't put any accidental combination that does not make a difference in the columns design. But here for the world's designed I will separate now calculate So we are calculating the sheer walls in order to set their steel reinforcement. This will only dig a few seconds. So the calculations are over. We are going to display the steel area. Remember that the direction X here is the global Z direction. Because of the Mary enforcement, direction is along easy access. And we chose it in the late and shelled reinforcement. Part minus and plus are for but them and took the enforcement. We can see there according to the local X access, the the local access. So we can see here then the local access. So the minuses or the bottom and plus is because there are two layers off steel reinforcement and a 30 centimeters work. So to remind you X is for the longitudinal reinforcement. And why is for the resented the enforcement now here? After the calculation, robots will give us the needed reinforcement for the world's. There are displayed in centimeters square meter. So guys, we're done with the sheer world design. Next we are going toe design the slaps 11. Slabs Design: Hey guys! And disgusting. We are going to design the doc's lab off This village is So I'm going toe open it in a new window on and turn off the finite elements. No, like we did for the world's he's all snaps. But this time I'm going to choose the local die. Action X is according to the global X axis. Now we have the same access for the local panel and globally, we are going to shoot the combination. Andi, display the moments they are expressed and song meter after meter. No, If we go into complex here we have the forces for calculating reinforcement. According toa food on our this method divides the moment off the ocean mx y into two portions, one off them, following the direction X and added toe M X and the other following the direction Why? And added tow em. Why So if you click on here, we have the doubly enforcement moments for eggs. Um so why? And we have about them reinforcements. They are also expressed and tone meter for meter. So this method will give you the moments. If you wanted toe calculate their reinforcement by yourselves. We can also use it for the world's. But if you want the calculation off the reinforcement done by robot, we are going to do the same that we did with wars. So I'm going to close this window and go toe RC design slab required reinforcement. We are going toe select the tox lab and no Blake and shell reinforcement that we will start from scratch and call it slaps. Now for the reinforcement calculations for shares, I will choose simple bending because our slab will not they compression or tension forces. As for the manly enforcement direction, we're first go to jail McCrie properties and local back in the direction click on X and we will see here the directions for the planet. The blue one is for the main direction. So it iss in the X direction. We see now that the local system and the mainly enforcement directions on the global system are all aligned, the bloom is for their main, the enforcement direction. So it is in the X direction. We are going to choose a long X axis here, So if we have a lot off slabs, we should check the direction for each one. Andi Timothy areas the rate for 20 reinforcement. We can choose the 16 millimeters both Andi at close. Now we have our slab. I will put it for this month. For now it is 131 on deploy. Now we have set our parameters for this lab. So you are going to choose here on the our slab and I'm going toe remove or saves make combinations and start my calculation. So what? This finished? We have no others or warnings. No, we can check the reinforcement and the deformation. So the x minus And why minus are for the bottom reinforcement. And the loss is for the top reinforcement. We have very enforcement and centimeters squared were Meet it and you can also check the selection. Could I? So it seems that the deflection in this lab is very small. We can shake that. The minimum reinforcement is similar with quiet three enforcement. So our slab requires the minimum reinforcement and doesn't have a big deflection. So, guys, this is it for this love design. In our next lesson, we are going to design the rest 12. Raft Design: guys in this final lesson, we are going to design a raft. First of all, we are going toe delete our supports in order to throw a raft. Then we're going to stand in the front view and select. I would her story. I'm going to give the raft and offset off 80 centimeters. So I'm going to select a column. This column will have ah translation Vector off minus 0.8 minus 0.80 Execute Now I'm going to do the same for their three other columns on the corners on I will define and you thickness or so I left 50 50 centimeters. We are not going toe, but it used the moment off. Inertia material See 25 Onda We will check the parameters or foundation elasticity. So this is the model is off sub great reaction usually given by general technical report. But if you don't have it, we can use the equation off bowels Okay, equal to 120 times the very swell capacity given by number, meter, square and the motherless off sub Great reaction by town were cubic meters. So of course the very excellent capacity will be given in the geotechnical report. In this case, I'm going to take it equal to 30 time per square meters. So okay, equal toe 3000 and 600. So even. And put the value here now for their K X and gay boy. They also should be given by their show technical report. But if they don't have them, I will keep them equal to zero. In this case, we have a small problem because Robert will consider the model unstable. But the solution is to add to the raft a fixed support in the X and Y directions. Of course, our model is stable and the X and Y directions do toe person pressure. Friction between complete and soil etcetera. Support tab and close. We have are a few left. We can. All right on. This is our rest. No off course. You're going to delete these columns? No, I'm going toe generate Appointed element match for our left. 11 sides were meter. Okay. And generate. So this is our left. Now I'm going to define a new set off supports called fixed X Y. Check the 1st 2 and I'm going to select good corner Nos. That's close? No, if we have some notes like this one here, we can select all the nose and there's delete. Apply. So we cleans over the molting? No, only going to select it there. Stand Open it in your window toe, begin the design. First of all results Maps, automatic direction coating to the X access can now check their sold reactions and deploy. Now, of course, we're going toe Choose going to Recalculates first and then you are going toe Choose our service load combinations to check our soul reactions So so reactions that plus live they are shown in tone per square meter. Now our bearing capacity is £30 per square meter So we are safe here now I'm going to go to their tow. This combination on you can see that we have values bigger than 30 ton per square meters. No, When we are verifying the soil pressure, using the say is make combinations. The code allows us to use and bearing so incapacity off 1.33 times our sore paving capacity which is in this case £40 per square meter. So there are values even greater than 40 in this case we can give the left a bigger offset or we can in this case give it a bigger thickness. Now for the reinforcement like we used earlier, they would an urban method. We can check the moments in the top and bottom part off the raft and the X and Y directions off course for the reinforcement. We are going to choose on ultimate limit state combination. We can also check the sheer forces. The sheer values on the left should not exceed the five BC value given by this equation, we can see the boy. Is there a 50.9 for the ref Lambda equal one halftime See? Be doubly one meter Andy is for a 50 centimeter left off course. If the values and robot are greater than the F C C value we can give, I would have a bigger thickness or we can out toys. Now for the final verification, we are going toe. Verify the punching shear dissolved Bagram for bars will exit this window. Choose the FX force with labels on deploy on. We're going to choose on ultimate limit state combination. Now, in this model we have the same dimensions for the condoms so we can take the highest value here. But if you have different dimensions for columns, we should take the biggest value off half X divided boy a times B on a and B are the columns dimensions. Now, according to the A C, I will have three equations for the calculation off B. C. We should do the three calculations and take the minimum for if we see between them, this five e c should be greater than F X. So we would not have toe some punching shear ties. So, guys, this is it with the ref design. Next, I'm gonna do a small announcement. 13. Thank You!: So, guys, now that our house is over, I want to say congrats to you own and thank you personally for taking part in it. If you have any question, you can fight me on my linked and or Instagram profiles on off course. You can ask them in the comments section I will be more than glad toe answer you or discuss with you structural engineering or any other topic. So, guys, don't be shy and get in touch. This is not the end. There will be more courses on, more softer to learn. So I hope to see you in another class on statement.
