Dear respected Engineers,
I am designing my first pipe rack using STAAD.pro 2007and IBC 2006/AISC Seismic Provisions. I'm using the load combinations stipulated in section 1605.2 and 1605.4 which leads to section 12.4.3 of ASCE 7-05. I need some clarifications please: .
1- Is the overstrength factor used to design all members of the structure?
2 - What does 1.1*Ry (or 1.1*Ry*Fy*Ag) represent? Is it applied to all members of the structure? how would you write it in STAAD editor?
Please advice. if I missed anything or if you have any tips for modeling pipe racks in STAAD and would like to share them.
Thank you.
