I am a bridge engineer. I somehow have to design CIP two-way slabs for a part of parking structure in San Jose. I have CA PE, but I never designed anything about building with seismic load, because I am working in Arizona and did only bridges for a living.
Anyway, I think I need to use equivalent frame analysis method in order to incorporate the lateral load with DL+LL in the two-way slab design. I read and read concrete design books, and finally understood what to do. However, I realized that analyzing the moment distribution method to come up with design moments for each patterned load cases with lateral loads are killing me, and therefore I am looking for how to simplify the analysis using beam analysis software using the calculated equivalent stiffness.
I have no idea how to cheat/use the equivalent stiffness calculated for the moment distribution method, with any typical 3-d modeling (STAAD)?
Anyone knows how to model the equivalent frame into STAAD or any 3-d FEA software, so that I do not need to do the moment distribution method each cases?
