单层索系柔性光伏支架抗风策略研究OA

Ordinary single-layer cable based flexible photovoltaic brackets have low wind resistance due to only one layer of cable,which limits their application range.A 15-metre span single-layer prestressed flexible photovoltaic bracket is taken as an example to analyze its wind resistance strategy,and calculates its cable internal force and deflection through numerical simulation analysis.The settlement shows that the single-layer cable based flexible photovoltaic bracket can significantly improve its wind resistance by setting an anchor structure at the mid span,and the displacement of the cable under wind suction conditions is significantly reduced.Compared to the design scheme that solely relies on increasing the diameter of the cable and increasing the pretension of the cable,the combination of single-layer cable system and ground anchor structure can significantly reduce the construction cost.
