青岛万达东方影都展示中心单层网壳结构设计

Structural design of single-layer lattice shell of Qingdao Wanda Oriental Cinema Exhibition Center

青岛万达东方影都展示中心造型为不规则的海螺形,为满足空间与视觉要求,主体钢结构采用大跨度单层网壳结构。介绍了工程结构体系、杆件截面选取等内容,分析了结构在各个荷载工况下的变形和内力,论述了结构整体稳定、典型节点做法等关键问题。结果表明:该结构体系的刚度和抗震性能良好,整体稳定性较好。

The modeling of Qingdao Wanda Oriental Cinema Exhibition Center is irregular nautilus. In order to meet the requirements of space and vision,the main steel structure adopts large-span single-layer lattice shell. The structural system and the selection of the member bar section were introduced. The structural deformation and internal force in every loading conditions were analyzed. Besides,the stability of the global structure and the practice of the typical joints were discussed as key problems. The results show that the stiffness and the seismic performance of the structure system are good and the stability of the global structure is great.
