47、rovides requirements for the design, fabrication, installation, and maintenance of single-membrane structures that are either reinforced or unreinforced and that are air-supported, frame-supported, or cable-supported.1.2The general requirements, structural design methods, loadings, and limit states

48、specified in this Standard are intended to be consistent with the National Building Code of Canada (NBCC), except where more detailed or stringent requirements are necessary for the structural adequacy and the long-term serviceability of structures.The requirements of this Standard are intended to a

49、pply to independent membrane-covered structures and structures that are contiguous with other structures and are attached through a common element.1.3This Standard does not apply to(a) multi-walled structures that are not supported by continuous air pressure;(b) air-beam-supported membrane structures using pressurized air as part of the support system; and(c) greenhouses that are not covered by Part 3 of the NBCC.1.4Other standards may be used for the design of air-, cable-, and frame-membrane supported structures where specified by this Standard.
