About this detail

Steel beams frame into a steel column utilizing a cap plate and shear plates welded to the beam webs. The cap plate thickness equals the greater beam flange thickness plus one-eighth inch using fifty ksi steel, joined to the column flange with a complete joint penetration weld and bevel welds. Shear plates connect to the beam webs with three seven-eighths inch diameter erection bolts, reduced to two bolts for W8 or W10 shapes, and welded to the beam web on three sides with a five-sixteenths inch fillet weld. A concrete slab over metal floor deck or roof deck bears above the structural framing, maintaining a minimum one inch depth clearance and two-thirds beam depth requirement.
