预应力弦支结构的张拉应力分析及过程监测

The research of prestressing suspend dome technique and monitoring

通过对太原煤炭交易中心展览中心采光屋面的张拉施工过程分析,发现本项目的主索力施工监测值与采用AN-SYS平台的预应力张拉模拟的计算基本和现场吻合,而次索的误差较大,需要进行调整。圆形弦支屋面因为场地受限所采用的分批次张拉也是可行的。

This article through to the Taiyuan Coal Trade Center Exhibition Center lighting roof of tensioning construction process analysis, found the main cable force monitoring of construction project value and uses the ANSYS platform to prestress tensioning simulation calculation funda- mental and site of the anastomosis, while the second cable of large error, need undertakes adjustment. Circular chord roof because of limited space using batch tensioning is feasible.
