Abstract

This paper introduces the 2004 version of the wind load provisions of the AU Recommendations for Loads on Buildings. One of the largest revisions is the introduction of wind directionality factor. If the building orientation is engineered, an economic design becomes possible that considers wind directionality. However, in this case, the combination of the along-wind force, crosswind force and torsional forces should be taken into account in the structural design not only for high-rise buildings but also for low- and medium-rise buildings. These are also introduced clearly in the provisions. The gust loading factor currently based on the tip displacement has been replaced by one based on the base bending moment. Other major revisions have been made on topographic effects, calculation formula for roof wind load, calculation formula for wind load on components and cladding, and aerodynamic shape factors.
