About this detail

A structural steel beam connects to a wide-flange column using a combination of welded flange connections and a bolted web connection. The top and bottom flanges of the beam are welded to the column with complete-joint-penetration groove welds. Continuity plates matching the beam flange thickness are installed inside the column web at the top and bottom flange levels, clipped per typical detail and secured with welds. A vertical connection plate is shop-welded to the column face and bolted to the beam web using slip-critical bolts spaced at three inches on center, maintaining minimum two-inch edge clearances. Additional stiffeners and continuity plates are positioned according to project notes to handle high rotational and shear forces.
