This article focuses on AISI S which applies to cold-formed steel structural members subject to gravity loading, wind loading, and seismic loading, except when specific seismic detailing is required. Aii shall lap aiai reinforcing a minimum of 25 inches mm. Light-framed construction shall be in accordance with Section Concrete slabs and footings shall be poured as a monolithic unit.
Reinforcing shall be continuous at corners using corner bars or bending; minimum lap is 25 inches mm.
Piles supporting structures shall be designed by a registered engineer or architect. But, why would AISI develop six discrete framing standards as opposed to one design manual? Inset porches, in accordance with Figure 1shall be permitted in accordance with the details in Figures 2 through 4.
