About this detail

A braced frame connection at Level 3 features a diagonal brace framing into a steel beam and column assembly. The brace connects using gusset plates measuring 3/4 inch by 12 inches by 1 foot 8 inches, welded with complete joint penetration and fillet welds on three sides. Stiffener plates, including sizes 3/4 inch by 12 inches and 1/2 inch, are welded to the column web and flanges to manage concentrated loads. Additional beam connections utilize two 7/8-inch-diameter A325 bolts configured per the type C1 detail for spacing and web requirements. All plate sizes, weld sizes, and maximum load criteria are designated per the structural drawings and load map notes.
