大连国际影视艺术中心骨架式膜结构的设计与施工

Designing and Constructing of Framework Membrane Structures for Dalian International Movie-television Art Center

大连国际影视艺术中心主体结构工程为骨架式膜结构,膜材直接覆盖在钢网壳上。结构分为两大部分,其主体部分为一个局部带肋的单层椭球壳,采用双层膜保温。对两种计算模型在几种荷载分布条件下的结构内力进行了计算分析。对结构的施工安装要注意的事项和双层膜的保温效果进行了探讨,分析结果表明,骨架式膜结构的整体性好,设计中可以不考虑膜的刚度。双层膜可以在我国北方寒冷地区采用。

Framework membrane structure is chosen as main structure for Dalian international movie-television art center, and its steel reticulated shell structure is directly covered by membrane. There are two parts in the project, and the main one is a single-layer ellipse shell with partial ribs, in which double-layer membrane is introduced to insulate heat. In particular, the designing and constructing process of the framework membrane structures of this project are presented.
