The foundation interface for a buckling-restrained braced frame column supported by a concrete frame footing and grade beam tied into an adjacent slab on grade. The concrete slab reinforcing matches the top bars and features number six Z-bars spaced at twelve inches on center staggered typically, with transverse bottom and top reinforcing having hooked ends extending to the top of the footing. Hairpins per schedule with alternate hooks and two rows of longitudinal top and bottom reinforcing are provided where indicated in the schedule. The footing surface is roughened to a one-quarter inch amplitude at block-outs, and Z-bar dowels are installed on all sides of the footing. Mechanical and other pipe penetrations are strictly prohibited throughout the footings and concrete beams above them.
