成都市文化宫新建工程的办公文体中心由高层建筑和倾斜大高差、大跨度网架构成,针对该复杂建筑,分别对高层建筑和网架进行分析设计。在此基础上进行了整体分析,考察了结构的整体性能。分别介绍了型钢混凝土组合截面转换桁架、电影城大悬挑钢桁架、管桁架膜结构、大跨度混凝土梁等难点的设计思路和构造措施。该工程建成后经历了汶川地震,主体结构保持完好,充分证明了结构设计的合理性。
The cultural center of Chengdu Cultural Palace Office of the new style of office by the high-rise buildings and inclined large elevation, large-span grid structure, for the complex building, respectively, for high-rise buildings and grid analysis and design. Based on this, a holistic analysis was carried out to examine the overall performance of the structure. The design ideas and structural measures for the difficult points such as the transition section of steel-concrete composite cross-section, the steel truss of cantilevered film city, the pipe truss membrane structure and the long-span concrete beam are respectively introduced. After the completion of the project, it experienced the Wenchuan earthquake and its main structure remained intact, which fully proved the rationality of structural design.
