That sort of detail is not discussed in building codes. My stairs (indoor) rest on the stringers. That said, what guidelines the IRC and IBC do narrow the field for what dimensional lumber you can use. This makes using the proper stringer width critical when constructing stairs. For example the IRC specifies that stairs shall be designed to withstand a live load of 40 pounds - as with a building floor. For the throat to be strong enough to support this load, it should be at least 3.5 inches wide, the same width as a 24. The following analysis demonstrates results of a typical wood-framed stair stringer configuration as well as several similar configurations. The stair waste itself require steel bars at the top in-order to accommodate the imposed tensile stresses on the cantilever. A. Field slopeable to all common stair stringer pitches, the LSCZ connector is suitable for either solid or notched stringers. Roof joists should be nominally 2" wide and 4" to 12" deep, although larger dimensions can be used. c. Individual stair treads shall be designed for the uniformly distributed live load or a 300-pound concentrated load acting over an area of 4 square inches, whichever produces the greater stresses. The stringers are already cut and are 12' long. Thus S12 50 designates an I-beam with a depth of 12 inches and a nominal weight of 50 pounds per foot.
