【摘要】 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。更多还原

【Abstract】 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.更多还原
