摘要
为研究固定式光伏支架的承载能力及破坏形态,对足尺钢结构支架进行静力试验及有限元分析。结果表明:支架结构的破坏特征主要为挠度变形破坏,支架结构的承载能力主要由挠度变形控制。试验结果与有限元分析结果吻合较好,可为太阳能光伏发电站的工程设计提供参考。
To investigate the bearing capacity and failure characteristic of the fixed photovoltaic bracket,the static tests and the finite element simulation of the full-size brackets were conducted.The results indicate that the failure characteristic of the fixed photovoltaic bracket is mainly the deflection deformation,which shows that the bearing capacity is controlled by the deflection deformation.The experimental data agree well with the predicted results of finite element analysis which can supply references for engineering design of solar energy station.
