About this detail

A framing beam intersects a supporting member utilizing a bolted web plate and a lower gusset plate. The supported beam features a top and bottom flange cope minimized in depth, connecting via seven-eighths-inch diameter A325-PT bolts in standard holes through both the beam web and a three-eighths-inch each side plate matching the girder width. A three-eighths-inch gusset plate welded below with one-quarter-inch fillet welds on three sides provides vertical bracing support. Bolt counts vary by beam size, requiring three bolts for W12 and W14 beams, four bolts for W16, five bolts for W18, six bolts for W21, and seven bolts for W24. When connection type SC-2 is required and dimension X is less than eight inches, exactly one bolt is provided.
