Abstract

A downburst simulator has been developed to investigate the characteristics of the velocity distribution and wind loads on buildings induced by downburst. The aim of the project is to propose a reasonable wind resistant design method for downbursts. The simulator consists of a blower that reproduces an impinging flow on the ground and a shatter that reproduces a pulsed jet. The blower can move at a constant speed on rails. It was found that the simulator can reproduce the non-stationary winds by downbursts.
