AISD seismic provisions

[Tdog67]

Fellers,

I want to clear something in my mind. We do mostly low seismic projects in the midwest. If we have SDC A-C are we required to use the Cd and the overstrength factor in designing our bracing connections for steel framed buildings? I am reveiwing the Seismic revisions and it states SDC D or higher are subject to the requirements

thanks

No, if you are in SDC C or lower, then you the AISC Seismic specs do not apply. You can use an R of 3 and design it just like a regular building with non-seismic connections.

Just pray that the New Madrid Fault is no larger than they think...
