About this detail

A steel beam frames into a steel column with top and bottom stiffener plates and a bolted shear plate connection, typically used in special force-resisting systems. The steel beam web connects to the steel column web and stiffener plates via a shear plate using three 7/8-inch diameter erection bolts, reduced to two bolts for W8 or W10 shapes. The shear plate thickness equals the beam web thickness plus 1/8 inch, welded with 5/16-inch fillet welds on three sides to the beam web and column web. The upper and lower structural steel stiffener plates are sized to the greater beam flange thickness plus 1/8 inch with 50 ksi steel, and welded to the column flange with 5/16-inch fillet welds. Complete joint penetration groove welds connect the top and bottom beam flanges to the stiffener plates, incorporating standard weld access holes. Concrete over metal floor deck bears adjacent to the column, aligning with the top of floor or roof level.
