RBS Ordinary Moment Frame

[Charlie Delta Whiskey]

Can an ordinary moment frame use an RBS connection? We have always done this and used the appropriate R and Omega values, but AISC 358-10 5.2 seems to suggest that RBS connections can only be used in SMF and IMF. Am I missing something? Thanks.

RBS and be used for OMF's. If you do this, you do not have to obey all the restrictions of AISC 358. Instead you only have to obey AISC 341.
