About this detail

These typical details define the geometry and connection requirements for steel cap plates on hollow structural section tube columns. The assembly consists of a three-quarter-inch thick steel cap plate welded to the top of the tube column, sized according to column width, beam width, and workable gauge dimensions. All cap plate bolts are seven-eighths-inch diameter ASTM A325N installed in standard holes unless noted otherwise. Type SCP-1 features a four-bolt configuration, while Type SCP-2 features a two-bolt configuration.
