Chris
most of the seismic coefficient recommendations that I have seen are, oddly enough, a result of the Kobe earthquake. The analysis of that event found, among other things, that a significant number of the unexpected failures resulted from poor connection design and poor welding at connections; typically fin plates. It is unlikely that this finding would have an effect of the spectral response requirements, but it is conceivable that some misguided soul may increase the G factor in order to overcome the problem. Ambulance at cliff bottom? Well sort of.

Cheers

Steve

Which documents? Do these requirements apply to the static coefficient approach or to response spectra analysis?
