Provides requirements for determining wind actions for use in structural design. It includes revised sections on combination factors and cantilevered roofs and new provisions for torsion and windborne debris testing. It also provides for the treatment of doors as openings, and increased local pressure factors. Wind speeds and direction factors are given for regions in Australia and New Zealand. Factors are provided to cover the environment around the structure, the geometry of the structure and the dynamic interaction of the structure with the wind.
