초록
In this study, the predictions of strong wind around 3 dimensional building shapes model (circular, square, rectangular and rectangular corner-cut), which are categorized by height was conducted using PIV system, and 20 experiments was carried out in the wind tunnel test. In the experiment, we measured the wind speed by building shapes with different angle at 0° and 45° and also we also measured it by building height (circular, square and rectangular) with 150m, 90m, 60m and 30m on full scale and the test wind directions were 0° and 45°. In this study the results from experiment by PIV system has been compared to the flow-field results of CFD simulation to know the validity of measured wind speed.
