About this detail

A structural steel braced frame column base connection bears on a concrete footing. The column is secured with a two-and-a-half-inch-thick base plate and a set of sixteen one-and-one-quarter-inch-diameter high-strength anchor bolts extending through the footing to a bottom plate. Stiffener plates matching the column flange thickness are welded to the column flanges and base plate with partial-joint-penetration welds and fillet welds. A two-and-one-half-inch maximum non-shrink grout layer is provided beneath the base plate. Slab-on-grade and continuous footing reinforcement are omitted for clarity, and similar conditions require a pedestal as specified on the foundation plan.
