The design of cold-formed stainless-steel structural members shall be in accordance with ASCE 8. Cold-formed steel light-frame construction shall comply with Section 2211 A . Where required, the seismic design of coldformed steel structures shall be in accordance with the additional provisions of Section 2210 A .2.

[OSHPD 1 & 4] Modify AISI S100 Chapter J (Connections and Joints, Section J7.2) by the following: Power-actuated fastener available strength shall not exceed those strengths determined in accordance with Section 1617A.1.20 of this code.

2210 A .1.1 Steel decks. The design and construction of cold-formed steel decks shall be in accordance with this section.

2210 A .1.1.1 Noncomposite steel floor decks. Noncomposite steel floor decks shall be permitted to be designed and constructed in accordance with ANSI/ SDI-NC1.0.

2210 A .1.1.2 Steel roof deck. Steel roof decks shall be permitted to be designed and constructed in accordance with ANSI/SDI-RD1.0. The base material thickness of steel deck shall not be less than 0.0359 inch (0.9 mm) (20 gage).

Exception: [DSA-SS] For single-story open struc- tures, the minimum deck thickness may be waived if the steel roof deck need not be used as the diaphragm and there are no suspended hangers or bracing for nonstructural components attached to the deck.

2210 A .1.1.3 Composite slabs on steel decks. Composite slabs of concrete and steel deck shall be permitted to be designed and constructed in accordance with SDI-C.

2210 A .2 Seismic requirements for cold-formed steel struc- tures. Where a response modification coefficient, R, in accordance with ASCE 7, Table 12.2-1, is used for the design of cold-formed steel structures, the structures shall be designed and detailed in accordance with the requirements of AISI S100 and AISI S400.
