Description
More complex building designs may include wings with shared walls that have extra considerations for bracing demand.
Think of the word ‘wings’, and it is likely to conjure images of a prison compound or a bird flying free. Both images are equally relevant when it comes to establishing the definitions of blocks and wings under NZS 3604:2011 Timber-framed buildings. The two must work together under wind and earthquake load to ensure they don’t fly free of their own accord.
Scope
