From my previous attachment,if you tick"add restraints on edge if corners have restraints", then the intermediate supports at the bottom points will be considered (it is not graphically displayed), you can check this, just by looking at the deflection of the wall and its joint reactions.

I mean etabs or robot can set one to same support performance 

because my project need to verify i know how correctly using robot through the etabs to do that.

i set the model is 31 storey so i use the first to compare the result to verity the correctly using robot

can see my model and give some comment to me ?

your support is not the same, you have linear pinned support in ARSAP and fixed linear support in ETABS

@Anonymous study this,https://www.csiamerica.com/products/etabs/watch-and-learn

 

I think you have all sufficient evidence that, if you have the same model and run it to any softwares the result will almost likely the same.

 

Its time for you to decide now, are you using ARSAP or ETABS or what?

 

If you decide using ARSAP stick to this forum and talk anything but ARSAP, but if you want another software go to their respective site or forum.

 

In this regard, and in fairness to you, this thread comes to a conclusion now.
