Technical
Advisory Note - Bracing Units
GoldenEdge - Medium Density Fibreboard
(MDF) Racking resistance of 9mm and 12mm GoldenEdge Regular MDF
and 6mm Thinline
Description,
Purpose and Application
GoldenEdge MDF has excellent strength
quality, surface smoothness and stability. It can be used to provide
sheet bracing resistance for light timber framed buildings under
wind and earthquake loading to meet the requirements of the New
Zealand Building Code section - B1 Structure and the 50 year durability
requirement of section - B2 Durability.
Testing
The New Zealand Building Code lists
NZS 3604:1999, "Timber framed buildings" as an Acceptable Solution
within B1/AS1 of the approved document under clause 3.0-Timber.
Clause 5.5.2 of NZS 3604 requires Bracing Unit (BU) ratings to be
determined by test. Clause 8.3.1.2 of NZS 3604 states that the bracing
capacity of wall bracing elements shall be determined by the BRANZ
P21 test procedure and rated in accordance with BRANZ supplement
P21 in Bracing Units (BU). Nelson Pine Industries Ltd commissioned
BRANZ to carry out tests in order to derive bracing ratings to be
used with NZS 3604:1999 for bracing walls constructed with bottom
plates bolted to a concrete foundation or coach screwed to a timber
foundation.
