Experiment study on wind resistant performance of standing seam roof system with anti-wind clip

Wind uplift failure occurred repeatedly in the standing seam roof system. On the one hand, there is a big difference between the modeling of the standing seam roof system in foreign countries and that in China, so the research results cannot be directly used. On the other hand, most domestic researches focus on the static performance of roof systems without anti-wind clip. The static experiment and dynamic loading experiment of the standing seam roof system were carried out, and the response change, ultimate bearing capacity and failure mode of the roof system under load were obtained. The research shows that the standing seam roof system has two main failure modes: occlusion failure and tearing failure, and the use of anti-wind clip and loading method will change the failure mode of the roof system. At the same time, dynamic loading, increasing the plate width and the spacing between the anti-wind clips, and not using the anti-wind clips will all reduce the ultimate bearing capacity of the roof system.
