Permanent bracing
Permanent bracing must be provided to enable the roof, wall and floor framework to resist the horizontal forces.
An appropriate connection is needed to transfer these forces through the framework and sub-floor structure to the building's foundation. When required, bracing within the building is to be constructed into walls or sub-floor supports and distributed evenly throughout. This bracing is normally in vertical planes.
Where buildings are more than one storey in height, wall bracing has to be designed for each storey.
