An HSS 6x6 member frames above a structural steel beam sized per plan, establishing a top of steel elevation of 157'-0" at the top cap plate. The underside of the roof deck sits at a nominal elevation of 155'-0". A 1/4-inch cap plate tops the vertical and horizontal hollow structural sections, joined with typical one-quarter-inch fillet welds. An L3x3 angle and outrigger connect the framing at the beam top flange, supplemented by an angle brace detailed per plan connected underneath the beam top flange.
