About this detail

A continuous wide-flange beam passes over the top of a wide-flange or alternate hollow structural section tube column. The connection features a Grade fifty cap plate or stiffener plate sized to match the beam or column flanges, specifying a thickness equal to or thicker than the column flanges. All complete joint penetration welds require back-up bar removal, back gouging, and a five-sixteenths inch fillet weld. Where an alternate tube column is used, two additional stiffeners are added at the center above the column, alongside a shear tab connection sized per the connection schedule.
