Description

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.

  • Irregular bracing can cause problems
  • Damage to Christchurch houses varied
