Re: 2007 cbc special seismic load combinations

[Subject Prev][Subject Next][Thread Prev][Thread Next]
FWIW, we are to use IBC 2006, which CBC 2007 is based on, and only refer to ASCE when specifically directed.  The special seismic load combos in IBC/CBC are different from the ASCE.  But, I have not seen otherwise.

Should we be using the CBC Equations 16-22 & 16-23 or ASCE 7-05  section Equations 6 & 8?


I do not find any reference in the CBC which requires the use of the ASCE equations. My confusion comes from the Seismic Design Manual Volume 2, Ex. 2 using the ASCE equations for the uplift of shear panel on a beam.
