About this detail

A steel column splice connection uses channel sections positioned on each side of the column web. The connection utilizes eight three-quarter-inch diameter A325 bolts with two washers each, standard holes in the column, and oversized holes in the channel, with one-inch diameter A490 bolts required for columns weighing over one hundred pounds per foot. Two channels are required, with one on each side of the web for columns over thirty feet long or weighing over one hundred pounds per foot. Partial-joint-penetration groove welds are specified on each flange sized per Table A, with an optional one-quarter-inch shop weld in lieu of the bottom four bolts. Shims are provided as required, and an optional two-and-a-half-inch maximum lifting hole is permitted in the channels.
