About this detail

A steel column splice connection joins an upper and lower column section using splice plates and bolts, with an option for shop welding the lower column web. The assembly incorporates a splice plate sized per the type one steel column splice table, featuring vertical slot holes in the upper column splice plate and filler plates as required. Bolt rows are spaced with specific dimensions such as two inches and three inches on center, and flange welds are applied typically to each flange. Five-sixteenth inch welds are specified on three sides at the contractor's option in lieu of shop bolts in the lower column web. Finishes comply with AISC standards, and dimensions reference the top of steel of the beam below.
