About this detail

A structural connection exists between a steel floor beam and a stair stringer supporting concrete-filled metal deck stairs. The stair stringer frames into a steel beam sized per plan, with a one-quarter inch thick stiffener plate welded at the channel connection. Fillet welds of three-sixteenths inch on three sides secure the assembly, alongside quarter-inch typical welds indicated throughout the connection. Stair pans act as a pour stop for the concrete over metal floor deck system as sized per architectural drawings. A general note directs the builder to refer to sheet 9/S511 for typical slab edge requirements.
