  • As a common building structure, metal roofs have been widely used in various large public buildings because of their unique advantages such as beautiful shape, light weight and high strength. However, there are still some limitations in the current research on the wind resistance of metal roofing. Therefore, this paper studies the wind resistance of large metal roofing under wind load based on wind tunnel tests on the background of the metal roofing project of Xiamen New International Expo Center. Through the wind tunnel testing, the stress state of the metal roofing under different wind speeds and wind angles was simulated. The distribution of force characteristics, equivalent wind load, and wind vibration coefficient were measured. The standard value of wind load of the envelope structure was obtained, and the two common calculation methods were compared. The envelope results of the two methods are safe in the calculation of the standard wind load of the envelope structure. Finally, the ANSYS finite element software was used to establish the metal roof model of the landside exhibition hall, and the wind vibration calculation was carried out. By analyzing the displacement time history and the equivalent wind load of typical joints, the overall wind load value which could be used in this project design was obtained. The stress characteristics and instability modes of metal roofing in a strong wind environment were summarized, and the factors affecting the wind resistance of metal roofing were analyzed. The strengthening measures for wind resistance design of metal roofing were put forward, including enhancing wind resistance connection and locking height, rational selection of materials and structures, so as to provide a certain theoretical guidance and scientific basis for the design of such structures in the future.
