| Abstract: | The performance of building envelopes is increasingly essential. Poor building envelope performance is regarded as one of the main reasons of damage to buildings under wind actions. The most frequently damaged parts of building envelopes are roof systems, so this research tests the endurance of structural integrity of modern roof systems under static and cyclic wind loads. In this dissertation, an experimental investigation has been carried out to obtain technical information on the structural behavior of metal roof systems in order to test the uplift resistance and dynamic performance under wind actions. Totally eighteen groups of tests are conducted on two types of panel-to-clip attachments. Six static tests on each panel-to-clip attachment consist of the same number of stepwise loading tests and impulse loading tests. Moreover, a standard dynamic loading protocol is carried out to assess dynamic performance of these metal roof systems with various installations. Two types of panel-to-clip attachments are different from their shapes of panel, which is trapezoidal and vertical. In this research project, comparison on the structural behaviors of these two types of panel-to-clip attachments is made from test data. It is useful for further research and understanding of the failure mechanism of the roof systems. It is important to suggest controllable seaming procedures during installations in practical use, which can improve resistance of structural metal roof systems against repeated wind actions as well as water tightness. |
