Dear viewers, I am yet again here with an informative and useful tutorial on Etabs. My previous tutorial was much liked and I get to know that people are interested in learning Etabs. The previous tutorial was a bit complex, so today I thought of making an easy tutorial of the example mentioned in Etabs Documentation and Tutorials. I will complete this modeling step by step in 2 tutorials. In today’s tutorial I am going to describe how to draw the columns in a building. So dear learners, here we go
This building has 4-storeys. Other specifications will be described during modeling.
1. Double click the Etabs icon on your desktop or from the Start Menu.
2.Click on ‘New Model’.
3. The following window appears, click ‘No’.
4.Now you have to enter the data for your model. In my case, X and Y grid spacing is same i.e 24′ and bottom storey height is 15′, also the typical storey height is 15′. Number of X and Y lines are 4 and number of storeys are 3.
5. Click ‘Grid Only’ and then click Ok.
6. Now your grid model will be displayed like below:
7. Now you have to define the properties of your model. First of all we would define Material Properties. Go to Define→Material Properties.
8. The following window will be displayed. Concrete and Steel are already defined in Etabs, so you can modify their properties or define any other material as well. My structure is concrete structure so I am going to modify the properties of concrete here.
9. When you click on modify, the following window appears. Change the properties according to your requirements. Click ok to close the dialog boxes.
10. Now you have to define the Frame sections (beams and columns). Go to Define→Frame Sections
11. The following box appears. Click to add a rectangular section.
12. The following box appears. This will be your Beam 1. Name the section and choose concrete in the material list. Write down the size of your beam, here I have taken 12*24. And click on the reinforcement.
13. The following dialog box will open. Click on beam and specify the top and bottom cover for rebars according to the requirement.
14. In the same way define Beam 2. Size of Beam 2 is 16*28.
Now again click on Add Rectangular to define the columns.
15. Name it Col1, choose material ‘concrete’. Write the dimensions of column. Here I have taken 12*12. Then click on reinforcement.
16.Specify the cover and then click ok. In the same way define Col 2. Its size is 14*14. Click ok to close the dialog boxes.
17. As my model is having same arrangement of beams and columns in all the three stories, so I want to place the beams and columns once in the 3 stories. So at the bottom of this window, I have chosen ‘similar stories’ option.
18. Now define the area section that is the slab. Go to Define→Wall/Slab/Deck Sections.
19. Slab1 is already defined. Click on modify/show section.
20. The following dialog box appears. Write down the thickness of your slab and bending (a usual practice is to use the value of one unit less than the thickness for bending). Choose your slab type. Click ok.
21. Now we will place the beams, columns and slab one by one. For this go to ‘Create Lines in Region’ as shown in the figure.
22. A small window appears. Here you will choose which beam you want to place first. Choose beam1.
23. Click on the lines where you have to place Beam1. Beams will be shown by yellow color.
24.In the same way select beam 2.
25. And place it on the required lines in the plan.
26. Now click on ‘Create Columns in Region’.
27. A small window appears. Choose Col1.
28. Click on the points where you have to place Col1. Columns will be shown by green colors.
29. Your model will look like this.
30. Now we have to place the slab. Click at ‘Create Areas’.
31. Choose Slab1.
32. Now one by one click on each panel. The boundary color will change indicating slab.
33. This is how your model looks after placing slab on all the panels.
33. Click on the small ‘tick ‘symbol indicating ‘Set Building View Options’.
34. Click on ‘Object Fill’ on the first column and then check the box at the bottom ‘Apply to All Windows’. Click Ok.
35. Now you can see the extruded view as shown below:
Thats all for now. I will soon upload the further procedure on how to assign the loads. Keep visiting Knowledgeoverflow.
