About this detail

Two structural steel column sections are joined at a splice line located four feet above the top of steel or at the contractor's option with approval by the engineer. The upper column bears on the lower column with filler plates provided as required and an optional lifting hole centered in the connection plate. The joint is secured using three-quarter-inch diameter A325 bolts with two washers each, typical. Channel sections, such as C6x10.5 for W8 columns, C7x12.25 for W10 columns, and C9x15 for W12 and above, reinforce the assembly. Partial joint penetration welds sized at t over two are applied to three sides along with five-sixteenth-inch fillets. Weld access holes are provided per typical details.
