摘要: 抗风性能和安全可靠度是强台风地区金属屋面的研究重点,钢板屋面抗风承载力强且经济环保,但相对铝镁锰屋面和不锈钢屋面的抗风研究薄弱。以深圳冰雪世界大跨屋面项目为例,基于钢屋面和光伏系统的抗风传力途径,阐述了增强型光伏组件、增强型抗风夹和增强型固定座等关键受力构件的测试研发过程。通过对钢屋面和光伏系统抗风揭试验,研究钢屋面荷载-应力和荷载-位移曲线,采集分析试验数据和破坏状态,量化了影响因子对上述抗风构造承载力的贡献水平。Abstract: Wind resistance performance and safety reliability are key research focuses for metal roofs in regions prone to strong typhoons. Steel plate roofs offer high wind-uplift resistance, economic efficiency, and environmental sustainability, but research on their wind resistance remains relatively limited compared to that on aluminum-magnesium-manganese and stainless steel roofs. This paper takes the long-span roof project of Shenzhen Ice and Snow World as a case study. Based on the wind force transmission mechanisms of the steel roof and the photovoltaic (PV) system, it elaborates on the testing and development process of key load-bearing components such as enhanced PV modules, reinforced wind-resistant clips, and enhanced mounting bases. Through wind uplift tests on both the steel roof system and the PV system, this study investigates the load-stress and load-displacement curves of the steel roof, collects and analyzes experimental data and failure modes, and quantifies the contribution levels of influencing factors to the wind resistance capacity of the aforementioned structural elements.
