| Outline of Final Research Achievements |
This study aims to develop tornado-induced load model and to clarify the mechanism of structural damage generation in a low-rise building with large span roof. First, the author carried out wind pressure experiments considering different size combinations of building model and vortex core using a tornado-like wind simulator. It was confirmed that peak wind force coefficients calculated by the proposed model can be consistent with experimental values. Next, by using Finite Element (FE) method, the presented methodology predicted successive stages of structural damage by a translating tornado. The results of FE analysis showed that the model case with a dominant opening is more vulnerable than the model case without it. The methodology described here enables accurate prediction of tornado-induced damage to cladding of low-rise buildings.
