Description

This article offers a solution to NZS 3604:2011 Timber-framed buildings clause 5.5.2, which has had callers to the BRANZ helpline scratching their heads.

Sometimes things don’t quite go according to plan and unintended errors creep in. A case in point is clause 5.5.2 of NZS 3604:2011 Timber-framed buildings covering subfloor bracing distribution, which clearly doesn’t make much sense.

The BRANZ helpline gets periodic enquiries about this one, so if you don’t understand it, you’re not alone. The revision of NZS 3604 should look like this: Subclauses (e) and (f) of 5.5.2.1 need to be deleted and clause 5.5.2.2 expanded to include the required minimum bracing values. 

Scope

This article includes:

• 5.5.2.1 Subfloor bracing systems – bracing lines
• 5.5.2.2 Minimum bracing capacity in subfloor bracing lines
• Will be in the revised NZS 3604
