About this detail

This structural steel detail shows a buckling-restrained braced frame column base plate connection complete with elevation and plan views alongside a base plate schedule. The steel column features a three-eighths-inch thick stiffener plate on the near side only, with doubler plates and complete joint penetration welds securing the column web to the base plate. A hollow structural section shear key extends downward into a concrete footing with one inch of non-shrink grout placed all around and inside the pipe, and the fill hole filled with grout. Anchor rods of grade one hundred five pass through washer plates and the base plate, anchored to the concrete foundation. An uplift plate extends from the base plate to tie into the brace gusset connection, supported by leveling plates or shims over a two-inch maximum non-shrink grout bed.
