摘要
屋顶槽式聚光镜在城区可以充分利用太阳能资源,绿色环保,但在屋顶安装高度约7 m的聚光镜,风荷载作用下会对屋顶结构产生强烈影响.以某5层框架结构为例,首先采用ANSYS软件建立安装槽式聚光镜前后的两种框架结构有限元模型;然后施加荷载,分别对结构模型进行静力计算,通过对顶层结构构件位移及内力对比分析,论证在风荷载下聚光镜对房屋顶层结构的影响,并提出了几种相应措施,可为安装在屋顶上的其他结构或设施的结构设计研究提供参考.
The roof groove type condenser can make full use of solar energy resources in the urban area,which is environmental protection.However,the condenser installed on the roof with a height of about 7 meters has a strong impact on the roof structure under the action of wind load.Taking a fivestory frame structure as an example,firstly,the finite element models of two kinds of frame strutures before and after installing the condenser are created based on ANSYS,and then loads are applied and the static calculation are performed separately through comparative analysis of the displacement and stress of the roof members,the influence of the condenser on the roof floor structure is demonstrated,and several corresponding measures are put forward,which provide reference for structural design research or facilities installed on the roof.
