About this detail

A skewed angle brace assembly ties into an existing wide-flange beam web and an open-web steel joist beyond. The diagonal bracing consists of two L4x4x1/4 angles skewed per plan, secured with three-quarter-inch-diameter A490 slip-critical bolts centered in the angle leg, with welded connections provided at the contractor's option. A three-eighths-inch bent plate accommodates the skewed connection at the beam web, backed by three-eighths-inch full-depth stiffener plates welded to the beam with five-sixteenths-inch fillet welds on three sides. The brace is further attached to the open-web joist top chord using an L5x5x5/16 angle connected via self-tapping screws and fillet welds.
