Seismic Base Shear in walls

476 Views, 3 Replies

For the residential building that I am designing, I have set up the core walls along the elevator shaft to act as shear walls.

I have put in the parameters for the seismic load calculations under the seismic load case definitions in robot.

On running the calculations, the program tells me the total base shear acting on the building in the X and Y direction.

However how do I find out what portion of the base shear is going into any particular shear wall. In other words, how do I find out which wall attracts what percentage of the total base shear?

As far as I know till now there's not a way to see automatically the % of shear that each wall gets.  You can only see what refaat wrote, the shear part "absorbed" by all walls and the shear absorbed by all the columns. You have to find out manually the % you want, by viewing forces table (to get values Fy and Fz for the columns) and table results for core walls (to get values WFx and WFy for core walls - notice that core walls values are refereed to global coordinate system) and-or viewing diagrams for bars and diagrams for buildings.

 base shear is going into any particular shear wall. 

 

Only in this way - Reduced Results table
