摘要

为研究装配式光伏支架结构在风荷载作用下的承载性能,以某光伏支架优化项目为基础,制作足尺光伏支架结构,进行静力加载试验研究,结合数值模拟,分析其力学性能。此外,研究了该支架结构在负风压工况下的受力性能。研究表明：结构在设计荷载下各构件未超过材料屈服应力,且挠度符合规范要求。有限元模拟与试验结果吻合较好,验证了有限元模拟方法的正确性。分析发现支架结构在140%设计荷载下有足够的承载力,结构破坏模式为钢梁局部失稳。

Abstract

Based on a photovoltaic bracket optimization project, a full-scale photovoltaic bracket structure is fabricated in order to study its bearing capacity under wind load. A static loading test, along with numerical simulations, is performed to evaluate the mechanical properties of the structure. Furthermore, the force response of the structure under negative wind pressure conditions is examined. The results indicate that the structural members remain within the material yield stress limits, and their deflections satisfy the code requirements. The finite element simulation closely matches the experimental results, validating the accuracy of the simulation method. In conclusion, the photovoltaic bracket structure exhibits adequate bearing capacity under 140% of the design load, with local instability of the steel beam identified as the primary mode of structural failure.
