About this detail

A structural steel connection frames a steel beam into a hollow structural section column at a freight elevator jamb. The steel beam connects to the column web via a shear plate utilizing three seven-eighths-inch diameter erection bolts, reduced to two bolts for W8 or W10 beams, with the plate thickness specified as the beam web thickness plus one-eighth inch. Fifty ksi stiffener plates are welded to each side of the column web matching the beam flange thickness plus one-eighth inch, secured with five-sixteenths-inch fillet welds. Complete joint penetration welds connect the beam flanges to the stiffener plates, incorporating typical weld access holes. Concrete over metal floor deck bears adjacent to the framing, maintaining a one-inch clearance at the elevator support column where two half-inch diameter deformed bar anchors are spaced at six-inch gauge centered on the jamb support column. A channel jamb and structural steel kicker brace are tied into the assembly per referenced structural drawings.
