Revision – AS1684.1 Design Criteria

A draft revision of AS 1684 Residential timber-framed construction: Part 1 Design criteria (AS 1684.1) has been completed and recently submitted to Standards Australia for approval as a project proposal.

AS1684.1 is a key standard for the timber industry as it defines the engineering design criteria used to design residential timber framed building elements (e.g. floor joists, wall studs) used in domestic dwellings and is used as the basis for generating solid wood member span tables.

The need for the revision was to bringing the design criteria in-line with recent changes made to relevant loading standards [imposed actions (dead and live loads), wind actions] and the timber engineering standard (AS 1720.1).
