I have a question regarding modeling a multi-tower building with a common podium. The building is 12 stories high and the podium is present in the first 3 stories only. Both towers have the same height. When modeling this in Etabs, should I consider the podium, tower 1 and tower 2 to be three differ...

I have a quesion about proper model, analyze and design using etabs , i have no clear way to assign partial fixity for column and shear wall base , according to BS 5950 , which shown in the figure , it depents on the rigidity of the connection between member and footing , and found no way to evalu...

Greetings! I am quite confused as to whether elements below grade (i.e. ground beams, columns extending to footings, tie beams, etc.) should be modelled in ETABS/STAAD. I have seen quite a few people consider these elements in their models (making the base of the model coincide with the top of th...

Hi Engineers I have to model a building with 4 basement levels. Do i need to include retaining walls on my Etabs model? Does Etabs differentiate between shear walls and retaining walls? What i am trying to avoid is to make my structure so stiff that it attracts a lot of forces while...

*SEFP Consistent Design* *Diaphragm Flexibility* *Doc No: 10-00-CD-0004* *Date: August 07, 2014* I am writing this article about a very important, but mostly neglected topic of flexibility of diaphragm. I used to assume that all reinforced concrete slabs can be treated as rigid diaphragms. But as i...

What are the code requirements for drift of a basement wall in seismic zone? Lateral earth pressure produces elastic deflections whereas seismic generate inelastic sway (after multiplying elastic by Cd/I in ASCE/IBC). Now how to combine both? and by what combination?
