Factors affecting the Site wind speed in Australian Standards

Written By: Lexatus - Sep• 14•13

In the previous article we have discussed about the Site wind speed. It is independent of the structure shape and has to be seen only as a wind speed characteristic for a specific site.

In fact, to determine the Site wind speed, the Structural Engineer takes the Regional wind speed and multiplies it by some factors. We have:

– Md – this factor considers the direction of commonly occurring wind events;

– Mz,cat – this factor considers the variation of wind speed with height;

– Mt – this factor considers the variation of wind speed on a specific site in function of topographic features such as mountains and hills;

– Ms – this factor considers the modification of wind speed caused by adjacent structures.
