About this detail

A structural detail features a steel beam-column moment connection with a diagonal brace framing into the joint. The column per plan receives a transverse girder per plan with complete joint penetration welds, backed by one-inch near-side and far-side stiffener plates with chamfered corners to avoid the column web k-area. A three-eighths-inch gusset plate connects the diagonal member to the beam top flange using five-sixteenths fillet welds on both sides. Doubler plates are welded to the column web for additional shear reinforcement. Various fillet and complete joint penetration weld sizes are specified throughout the connection for seismic force-resisting system compliance.
