About this detail

A shallow supported steel beam connection is reinforced with Grade 50 steel plates and high-strength bolts. The assembly incorporates top and bottom plates sized to match the beam flange, secured with five-sixteenth inch fillet welds on each side and designed with specific dimensional offsets relative to the flange width. A vertical web plate, either one-half inch thick or matched to a thicker beam web, connects using a maximum number of three-quarter inch diameter ASTM A325 bolts. Complete joint penetration welds and standard fillet welds are specified throughout the connection based on structural engineering requirements for shallow depth framing conditions.
