AS 1684 Section 8 requires permanent bracing be provided to enable the roof, wall and floor framework to resist horizontal forces applied to the building (racking forces). Appropriate connection is also required to transfer these forces through the framework and subfloor structure to the building's foundation.
Where required, bracing within the building will normally occur in vertical planes and be incorporated in walls or sub-floor supports and be distributed evenly throughout. Where buildings are more than one storey in height, wall bracing will be required to be designed for each storey.
