What would be the best way to model a sure-board shear wall in RISA-3D to accurately reflect it's rigidity? I have a relatively small two story building with a flexible roof diaphragm with a rigid 2nd floor diaphragm. The lateral system consists of a masonry wall and sure-board shear walls in...
I've been directed to use the ASD load combo(.6-.14 Sds)D + .7 rho Qe to design for overturning and soil bearing on a continuous braced frame footing. And then to use the Strength Design load combo (.9-.2 Sds)D + Omega Qe to design the reinforcing steel in the foundation.
My 4' wide foundation...
Thanks to all of you for your help. It looks as if there are multiple ways to look at it. In my original design I used GCp = 2.8 from Figure 6-17 (zone 3). That seams conservative and it works for the desired architectural WT profile, but wasn't sure if that approach was correct. It'll be...
I'm designing a flat, cantilevered steel canopy at a height of 18' on a building that has a roof mean height of 67'. It's relatively small...cantilevers out 11.5' and is only 25' wide with WT's at 5'o.c. The overall building length is 200'.
What is the correct procedure to find the vertical...
