About this detail

Steel floor or roof beams frame into a continuous steel column utilizing a gravity moment connection detail. The top and bottom beam flanges attach to the column with complete-joint-penetration welds and include weld access holes. The beam web connects to the column via a shear plate with three seven-eighths-inch diameter erection bolts, reduced to two bolts for W8 or W10 framing. Plate thicknesses equal the beam web thickness plus one-eighth inch typically, while stiffener plates equal the greater beam flange thickness plus one-eighth inch using 50 KSI steel. Fillet welds measuring five-sixteenths inch are applied to three sides as indicated.
