［提要］大連國際影視藝術(shù)中心主體結(jié)構(gòu)工程為骨架式膜結(jié)構(gòu)，膜材直接覆蓋在鋼網(wǎng)殼上。結(jié)構(gòu)分為兩大部分，其主體部分為一個(gè)局部帶肋的單層橢球殼，采用雙層膜保溫。對兩種計(jì)算模型在幾種荷載分布條件下的結(jié)構(gòu)內(nèi)力進(jìn)行了計(jì)算分析。對結(jié)構(gòu)的施工安裝要注意的事項(xiàng)和雙層膜的保溫效果進(jìn)行了探討，分析結(jié)果表明，骨架式膜結(jié)構(gòu)的整體性好，設(shè)計(jì)中可以不考慮膜的剛度。雙層膜可以在我國北方寒冷地區(qū)采用。
［關(guān)鍵詞］膜結(jié)構(gòu)；骨架式膜結(jié)構(gòu)；穩(wěn)定分析
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.
