单层预应力悬索光伏支架风振响应分析

Wind vibration response analysis of single-layer cable flexible photovoltaic bracket

应用SAP2000有限元软件建立一排三跨单层预应力悬索光伏支架模型。对悬索支架施加脉动风荷载进行时程分析,研究其在脉动风荷载作用下的风振响应,并与静力荷载作用下的位移进行比较。结果表明单层悬索支架在脉动风荷载下有更大的竖向位移和索力,风振响应明显。分析结果可为悬索支架结构设计提供参考。

SAP2000 finite element software is used to establish a row of three span single layer cable flexible photovoltaic support model.The time-history analysis of the photovoltaic support structure under dynamic wind load was carried out to study the wind vibration response under dynamic wind load,and the displacement was compared with that under static load.The results show that the flexible photovoltaic bracket has larger vertical displacement under dynamic wind load,and wind vibration has great influence.lt provides a reference for the design of large-span flexible photovoltaic support structure in the future.
