About this detail

A stair stringer connects to a structural steel beam supporting a concrete floor over a metal deck at the stair landing. A continuous deck bearing angle sized as L5x3x1/4 connects to the steel beam with a three-sixteenths inch weld at twelve inches on center. The stair stringer top and bottom flanges weld to the support framing with a complete joint penetration weld, while the web connects with a one-quarter inch fillet weld. Stair pans coordinate with architectural drawings and serve as a pour stop for the concrete slab.
