Re: FEMA-350 and 2001 CBC

Well, if they are OMF, then I believe pre-northridge connections with some slight modifications to weld material and backing bar stuff are still allowed in FEMA 350.

My Experience has been that cities will have amendments on their website saying words to the effect that AISC Seismic Code are to be used which I believe references FEMA connections.

If someone is designing SMRF, you can certainly require them to design to FEMA 350.

A question for those practicing in California.  Is there anything within
the California Building Code that would require the engineer to design
his moment frame connections using the FEMA-350 guidelines?  I'm
reviewing a project where the engineer has OMF frames that he basically
has designed as pre-Northridge.  I typically use RBS connections for my
frames but I cannot find backing for not permitting his design.
