异形单层网壳结构整体提升施工数值分析及应用

Numerical Analysis and Application of Integral Lifting for Specially-shaped Single-layer Reticulated Shell

结合徐州苏宁广场裙楼采光天井工程,对常规的网壳安装方法进行归纳总结。通过数值模拟进行可行性分析、验证,成功克服了该工程椭圆抛物面异形网壳结构安装定位困难、空间受限影响网壳结构整体性以及狭小场地限制的诸多困难,顺利实现了该异形网壳结构的整体提升安装。

Based on the roof project of Xuzhou Suning Plaza,the conventional methods for the installation of reticulated shell were summarized. Through the numerical simulation and analysis methods,the feasibility of the program had been verified,which successfully overcomed the difficulties of installation and positioning of elliptic parabolic shaped reticulated shell structures,space limit affecting the integrity of the reticulated shell structure and narrow space constraints,and successfully realized the overall lifting and installation of the deformed reticulated shell structure.
