BRACING OF A TIMBER-FRAMED BUILDING is required to resist horizontal wind and earth-quake loads.

The bracing demand to resist wind is expressed in bracing units (BUs) per lineal metre and bracing units per square metre for earthquakes. This compilation of articles from Build magazine looks at the bracing requirements for buildings built in accordance with NZS 3604:2011 Timber-framed buildings.

It starts by looking at what information is needed to start calculating bracing and to determine what needs to be provided for bracing calculations. It then works its way through the bracing requirements for various parts of the building, from subfloor to wall to roof, using examples to illustrate how to apply NZS 3604:2011.
