two way slab design question

two way slab design question

two way slab design question

(OP)
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?
 

RE: two way slab design question

just download the demo version of pcaslab from pca website. Its good for 15 day trial or just purchase the software its only like 1500.
