Hello -
I'm working on a project with concrete shear walls as the main lateral force resisting system. From my reading it appears using a surface model would be best (but please correct me if i'm wrong). I found a sample STAAD file SURFACEMODEL.STD and need help interpreting the results. After running the file, in post-processing I see two result tabs "Surface forces at X (local)" and "Surface forces at local Y (local)"...why? What forces do I use to design my shear wall? I would appreciate any help.
Thanks! Dennis
