Abstract

This research focuses on the influence of tornadoes, which are severe local weather disturbances, for wind resistant design of buildings. Because it was very difficult to evaluate tornado winds generated in real scale, a tornado simulator was developed in the laboratory and tornado-like flow was measured. The situation in which the form of the tornado-like flow changed depending on swirl ratio and surface roughness was reproduced, and the distribution of wind speeds according to this form became clear. These experiment results showed agreement with similar previous experiment results.
