About this detail

Beam and girder framing connections occur at an interior hollow structural section or pipe column. The assembly features a cap plate flush with the top of steel and matching the column wall thickness, with a knife plate required along the girder line. WT stem or knife plate thicknesses are sized per schedule 'a' with standard offset dimensions from the column centerline. Beams connect via typical bolted shear plate connections. The plan section details welded plate conditions where the edge of flange is flush with the face of column or overrun as required, cut to provide a quarter-inch minimum flat beyond the toe of the weld.
