Optimization of Reduced Beam Sections (RBS) for Ductile Detailing of Seismic Joint Connections Using Finite Element Analysis (FEA)

Steel structures used as Special Moment Resisting Frames (SMRF) designed to resist lateral loads (due to wind and seismic) are expected to undergo large inelastic deformations, hence the ductility requirements are explicitly stated in almost all standards. In any given frame, inelastic deformations...
