Structural framing design considerations for engineers and architects - Electronic Blueprint 
All buildings must be adequately supported against lateral wind loads, as specified in AS 1170.2 and AS 4055. In some cases, lateral earthquake loads may be a design criterion. The bracing requirements should be determined for the appropriate Region, Terrain Category, Topography and Shielding and recorded on the drawings by the design engineer. The Engineer or Architect should ensure that all structural timber products comply with the relevant Standards, including the branding requirements, as specified in the BCA and in the specifications. As part of the quality management process, the Builder should provide documentation of such compliance and branding. There have been concerns raised in Australia over the compliance and branding of structural plywood. The relevant standards are AS 1720.1, AS 1684 and AS 2269, which set out requirements in respect of manufacture, grading, finishing and branding of structural plywood; as well as other properties for various stress grades. If structural plywood is not correctly branded, or if the branding indicates non-compliance with the specification, the plywood should not be used for structural purposes. Organizations accredited to certify such products, and the products certified to AS/NZS 2269, are listed on the JAS-ANZ website.
