Summary | The tornado-like wind simulator was constructed in order to experimentally evaluate the characteristics of tornado-induced wind loads and the risk of flying-debris attack on buildings. In this study, we evaluated the relation between experimental simulator settings such as angle of vane and Rankine model-related parameters. The results of PIV and wind pressure measurements showed the good agreement of experimental flow with the model characteristics. Next, we tried to develop the model for wind force coefficients on the roof based on the Rankine vortex model. It was shown that the model can agree with the characteristics of the experimental results. |
