While the bracing requirements in NZS 3604:2011 Timber-framed buildings suit most buildings, the distribution rules of clause 5.4.7 are too lenient for some complex designs. During earthquakes, some Building Code-compliant buildings may move or flex, causing extensive damage. BRANZ research found which buildings are affected and suggests changes.

Changes are needed after houses with a mixture of NZS 3604:2011 wall bracing and specifically designed bracing performed poorly during the Canterbury earthquakes. BRANZ’s new design procedure for seismic bracing elements in new houses will help.

When builders are on site to carry out home renovations or repairs, it is a good time to suggest strengthening the property’s earthquake resistance with actions ranging from removing chimneys to securing the foundations.
