About this detail

Buckling-restrained braced frame beams frame into the top of a structural steel column with cap plates matching the thickest beam flange thickness plus one-eighth inch with a half-inch minimum thickness. A shear plate connects the beam web with welds and fasteners sized per schedule. Cap plates attach to column webs with three-eighth-inch welds and to column flanges with five-sixteenth-inch typical welds. Continuity plates are provided on each side where drag beams occur. Horizontal continuity plates are installed at bottom flanges of opposite beams if distance "d" exceeds three inches, while a sloping continuity plate is provided between bottom beam flanges if distance "d" is less than three inches. Complete joint penetration demand critical welds are specified for critical locations.
