A typical connection for a buckling-restrained brace at both the top and bottom locations along a strong-axis steel column and intersecting beam incorporates gusset plates connected to the column and beam flanges, with work points defined at the center of the column and half-actual beam depth as well as at the face of the column and beam for frame NE6C. Doubler plates are included per the corebrace connection schedule where required, and layout procedures reference subsidiary details for precise positioning. Weld symbols and plate dimensions are designated with variable notation to accommodate specific engineering requirements.
