About this detail

A dowel-laminated timber slab bears on the top flange of a structural steel beam, with a minimum three-inch bearing width. A concrete topping slab sits above an acoustic mat and a plywood layer over the timber decking, while a gap of one-half to three-quarters of an inch is maintained between panels. The timber decking consists of dowel-laminated two-by-ten sawn lumber, with glued-laminated or gang-nailed lumber permitted at the contractor's option. Additional information is referenced on the typical timber floor slab detail.
