摘　　要：近年来，随着现代建筑技术发展,人们对于建筑美观的要求越来越高。形式繁多的轻质、大跨、美观的金属屋面出现在地铁、航站楼、客运站等重要结构中。但是，随着金属系统的应用，多个屋面系统在实际应用过程中被风吹开，其抗风揭问题越来越明显。因此，研究金属屋面系统的抗风揭性能具有重要的意义。以直立锁边屋面系统为研究对象，通过试验方法和数值模拟研究其抗风揭性能。结果表明：直立锁边屋面系统抗风揭能力的最薄弱部位位于支座与屋面板的锁边处，在该位置处增加设置风夹可明显改善其抗风揭性能，并大幅提高该屋面系统的抗风揭能力。In recent years, with the development of mudern building techniques, there are more and more demands for beautiful buildings. A variety of lightweight, long-span, and beautiful metal roofs have been used in important structures such as suhways, terminals, and passenger stations,However, several roof systems have been blown open in real structures, and the problem of wind uplift resistance is becoming increasingly obvious. Then, the research on the wind uplift resistance of roof system is of great importance. The paper studied the wind uplift resistance of a standing seam roof system through experiments. The test results showed that the seaming lockrand place between the roof plate and support was the weakest region during the wind test; the wind resistance clamp could be improved by installing wind resistant clamp at the seaming lockrand place, and then improved the wind uplift resistance of the roof system.
