About this detail

A steel beam frames into a steel column with continuity plates and a welded shear plate connection. The structural steel beam connects to the column web via a shear plate secured with three seven-eighth inch diameter erection bolts, reduced to two bolts for W8 or W10 shapes. A five-sixteenth inch fillet weld connects the shear plate to the beam web on three sides. Continuity stiffener plates of 50 KSI steel are welded to the column web with five-sixteenth inch fillet welds, matching a thickness equal to the greater beam flange thickness plus one-eighth inch. Complete joint penetration welds connect the beam flanges to the stiffener plates, incorporating a standard weld access hole. A concrete slab over metal floor deck bears above the steel framing members.
