摘要
基于剪式单元,结合预应力技术,开发出适用于中大跨度的预应力索拱开合结构。并以60 m跨度的预应力索拱开合结构为例,采用通用有限元软件ABAQUS对其进行了运动过程分析、静力分析和整体稳定性分析,得到开启过程和闭合状态的受力特性,可为设计预应力索拱开合屋盖提供技术支持和参考。
The prestressed cable-arch retractable structure,which is based on the scissor-like unit and prestress technology,was developed for middle-span and large-span roof. As an example of the prestressed cable-arch roof with the span of 60 m,the movement process analysis,static analysis and the stability analysis were carried out by the software Abaqus. Then the mechanical property,which is of the deploying process and final closed position,were obtained. The finite element analysis results were given,which could provide the technical support for the design of the prestressed cablearch retractable structures.
