About this detail

A beam-to-column flange connection features a bolted shear tab and demand-critical complete joint penetration welds at the beam web and flanges. Stiffener plates matching the beam flange thickness are welded to the column, with weld access holes conforming to AWS D1.8 requirements. Bottom flange backing bars are removed, the root pass is backgouged, and a continuous five-sixteenths-inch minimum fillet weld is applied between the underside of the beam flange and the column flange. Top flange backing bars are attached to the column flange by a five-sixteenths-inch continuous fillet weld on the edge below the groove weld. Erection welds are provided with a minimum size of one-quarter inch.
