    SAI Global - Standards, Training & Certification

    Timber Framing Code AS 1684 has been further amended to meet the needs of designers and builders, and now covers a wider range of acceptable practices with more technical explanations included.

    According to the Timber Advisory Network, the most recent amendment to AS 1684, No. 4, addresses a series of changes to Parts 2, 3 and 4 of the Timber Framing Code. These changes will be called up under Amendment 11 to the BCA and are effective from 1 July 2002.

    They include:

    - new alternatives for top plate combinations

    - concessions and simplification of tie-down in low wind speed areas for coupled pitched roofs

    - extended use of 3.05 dia. gun nails as ‘nominal nailing’

    - closer alignment of Part 2 and Part 4 with respect to roof tie-down and connections at the top and bottom of bracing walls

    - amendment of the bottom fixings of bracing walls to align with manufacturers specifications

    - additional screw fixing tie-down details and amendments to some of the other fixing strengths to achieve consistency

    - underbatten sizes

    - tie-down strength for plywood (bracing)
