Hi everyone,
I have modeled a building containing shear walls as well as a moment frame. In modelling the shear walls I used surface entities and applied uniformly distributed loads onto the beams (udls) above them, I've also run the design shear wall command in staad as well. After the analysis of the structure I realized that when I am in post-processing and under the tab surface, the forces are split into surface forces at X (local) and surface forces at Y (local), and are reported as per the division of the surface. I am trying to design the reinforcement for the walls manually so as to confirm the design result from staad, however I am not sure which values to use from the tables in the post processing section. Could anyone help me in deriving the shear, axial and bending moments required for manually designing the wall from these tables.
NOTE: Staad file is attached below.
