P398: Joints in Steel Construction: Moment-Resisting ...
www.steelconstruction.infostrength. Moment-resisting joints will usually be rigid and either full or partial strength and thus the joints are either continuous or semi-continuous. In most situations, the design intent would be that moment-resisting joints are rigid, and modelled as such in the frame analysis 0F0F *. If the joints were in fact
Seismic Design of Reinforced Concrete Special Moment …
nvlpubs.nist.govThese moment-resisting frames are called “special moment frames” because of these additional requirements, which improve the seismic resistance in comparison with less stringently detailed intermediate and ordinary moment frames. The design …
