About this detail

A steel beam frames into a hollow structural section column with a moment connection. The top and bottom flanges of the steel beam connect to the hollow structural section column with complete joint penetration welds, supplemented by typical one-inch returns and five-sixteenth inch fillet welds. A web plate made of fifty kilopounds per square inch steel is sized to the beam web thickness plus one-eighth inch and fastens with three seven-eighth inch diameter erection bolts on each side. A bearing plate measuring one-half inch thick supports the assembly, with a note specifying that the bearing plate thickness shall increase to three-quarters inch where the depth of the supported member exceeds eighteen inches. A web stiffener plate is provided as required per general structural notes. Typical weld access holes are detailed at the beam web and flange intersections, maintaining a minimum depth equal to two-thirds of the beam depth.
