This structural steel connection details a buckling-restrained braced frame assembly framing into a W30 beam web and column. W21 braces connect to gusset plates designed by the buckling-restrained brace supplier, featuring an angle range between thirty and forty-five degrees. The assembly incorporates three-quarter-inch thick plates with a yield strength of fifty ksi, including column side plates interrupted at the bottom flange plate. Five-sixteenth-inch fillet welds secure the plates, and plate thicknesses match the beam web where specified.
