［提要］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。

Designing and Constructing of Framework Membrane Structures for Dalian International Movietelevision Art Center/Wang Lichang1, Shang Chunyu1, Gong Jinghai2 (1 Dalian Architectural Design and Research Institute, Dalian 116021,China; 2 Shanghai Jiaotong University， Shanghai 200011,China)Abstract:Framework membrane structure is chosen as main structure for Dalian internation
al 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.
