Assessment of Environmental Wind Conditions by Wind Tunnel Model Studies

摘要

In recent years, there has been a growing awareness amongst architects, designers and their clients of the significance of environmental wind conditions in the design of major building developments. As a reslt, some of these developments have become the subject of wind tunnel model tests carried out at the Department of Civil Engineering of the University of Sydney. In this paper, the acceptance criteria for environmental wind conditions used in these wind tunnel model tests are discussed. These criteria are compared with other published criteria, in particular the now well accepted criteria of Melbourne, and are shown to be in good agreement. The techniques used in conducting these wind tunnel model tests and the probabilistic technique used in the assessment of the prospective environmental wind conditions are discussed. Examples are drawn from two investigations carried out in the University of Sydney to illustrate these techniques.
