| Research Abstract |
In this study, we designed and developed a tornado-like wind simulator in order to comprehensively evaluate tornado-induced hazard to buildings. Using this simulator, characteristics of wind pressure on a low-rise building model were evaluated and collision of flying debris on a building model was experimentally simulated. Tornado-induced wind force model, which illustrates relation between wind force magnitude and condition of leakage and opening, was also proposed based on the characteristics of wind pressure on the roof.
