About this detail

A structural steel roof step connection features a continuous metal roof deck bearing on a steel joist and a supporting steel beam. The upper roof level terminates with a continuous one-quarter-inch bent plate. The steel joist sits on a steel cap plate at the beam below, secured with a five-inch deep joist bearing end utilizing two A325 erection bolts. These bolts are one-half inch in diameter at K-series joists and three-quarters of an inch in diameter at long-span joists. A one-quarter-inch plate is continuously welded to the beam flange, while an L4x4x1-quarter angle is spaced at six feet on center with a one-quarter-inch by five-inch by five-inch welded plate.
