Abstract
Metal roofing materials are often damaged during a strong wind event such as a typhoon or a tornado. In order to investigate the failure mechanism and the wind resistance of metal roofing materials, we have conducted a full-scale experiment using Pressure Loading Actuators (PLAs). In the experiment, two types of loading, i.e., dynamic loading simulated by using a wind tunnel test data and ramp loading, are applied to the specimens with metal roofing system assembled with the same way as that used for practical roofs of wooden houses. The experimental results indicate that the failure load of the roof under ramp loading is smaller than that under dynamic loading.
