无锡万象城天幕工程双曲单层网壳结构施工技术

Construction of the Hyperbolic Single-layer Reticulated Shell Structure of Wuxi Vientiane City

双曲单层网壳结构节点受力较为复杂,杆件制作精度高,安装定位难,施工难度较大。对无锡万象城天幕工程双曲抛物面单层网壳结构的重难点问题进行了介绍,如安装精度、整体稳定性、天幕铰支座等,并针对重难点给出了本工程的解决方法。

The behaviors of joints for hyperbolic single-layer reticulated shell structure are very complex. The requirements for fabrication precision of members are very high, and the installation and positioning of members is difficult. Some key and difficult points including installation precision, integral stability and the hinge support with their solutions are introduced for construction of the hyperbolic single-layer reticulated shell structure in Wuxi Vientiane City.
