ACI-318-08/UBC Load Combination States
1.2D+1.0E
Where E = Earthquake Load
UBC 97 Section 1630 States
E= p Eh + Ev,
Em= Omega Eh,
Where Eh = Base shear V.
My question is
1. Does Staad, Sap consider this equations when doing auto generation for load combination. because i checked staad for seismic on self wt and it used the E = V, which by above equations is not right. I assume software is doing it right and i am not looking it correctly .. so if any one can explain .... please do.
2. what are the conditions (If any ) in which i can take E= V?
p= 2-20/Rmax*sqrt(AB)
Say i am designing a Pipe Rack or an equipment structure, What shall i use in AB? there is no slab element...
CAN ANY ONE HELP ME OUT HERE?... AND EXPLAIN HOW THIS WORKS
