About this detail

A structural detail for a typical roof platform beam-to-column connection incorporating knee bracing at an HSS column supporting wide-flange beams sized per plan. Gusset plates made from ASTM A572 Grade 50 steel connect the 6x6x3/4 structural tube braces to the framing using three 1-1/4 inch diameter A325-X bolts typically. Five-sixteenth-inch fillet welds with a twenty-one-inch minimum length secure the gusset plates. Plan views show configurations for two-way, three-way, and four-way brace connections with continuity plates at splices.
