About this detail

A buckling restrained brace connects to a steel column and steel frame beam using a gusset plate and shear tab assembly. The steel beam attaches to the steel column with a shear plate featuring three seven-eighths-inch diameter erection bolts and a plate thickness equal to the beam web thickness plus one-eighth inch. Complete joint penetration welds secure the beam top and bottom flanges to the column, and stiffener plates are provided on the near side and far side with thickness equal to the greater beam flange thickness plus one-eighth inch. The buckling restrained brace core, gusset plate, and connection details are provided by the brace supplier, including specified web stiffeners as required. Foam blockouts of one inch and three inches are detailed around the brace casing and lugs to accommodate concrete encasement clearances.
