Abstract
Light-gauge steel roof system has the advantages of light weight, good seismic performance and ease for installation, which is widely used in large-span space structures. However, the roof system is often damaged under typhoon scenarios. Numerous accidents show that roof failure is mainly caused by the failure of roof panel connectors. In this paper, based on an existing industrial building with a 360-degree standing seam metal roof system, the finite element model is established using spring elements, and the failure process is simulated. Comparing with the existing wind resistance test, the numerical simulation method is verified. The ultimate bearing capacity and anti-wind exposure ability of the roof system were introduced. It is shown that the finite element analysis results agree well with the experimental results, which can verify the finite element model. The research results can provide the reference for the wind resistance design and performance evaluation of the roof system with a 360-degree standing seam sliding clip.
