About this detail

A concrete slab over metal floor deck or roof deck bears continuously across the top flange of the steel beams and column cap plate. The steel column top features a cap plate sized to the greater beam flange thickness plus one-eighth inch using fifty ksi steel, welded with a complete joint penetration weld. Steel beams connect to the column flange using shear plates welded on three sides with five-sixteenths inch fillet welds and bolted with three seven-eighths inch diameter erection bolts, reduced to two bolts for W8 or W10 shapes. A weld access hole is provided at the beam web and flange intersection. Bevel cuts are applied to the column flange as specified by dimension standards.
