About this detail

A steel column splice connection uses channel sections positioned on each side of the column flanges. The assembly incorporates thirteen-sixteenths inch diameter holes in the column and fifteen-sixteenths inch diameter holes in the channel, with sizes varying from C6x10.5 for W8 columns up to C15x33.9 for W33 and W36 columns. Three-quarter inch diameter A325 bolts with two washers each secure the channels, with an optional 5/16-inch fillet weld on three sides in lieu of bolts at the contractor's option. Complete joint penetration groove welds are specified at the column splice, accompanied by weld access holes and optional ceramic backing plates with an approved procedure qualification record. Shims are provided as required, and an optional lifting hole is located four feet above the top of steel or at the contractor's option with engineer approval.
