成都市文化宫新建工程结构设计

Structural design of Chengdu New Culture Palace

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。

Chengdu New Culture Palace is composed by tall building and inclined large-span grid structure.The tall building structure and the gird structure were firstly analyzed separately.Then they were assembled and analyzed as the entire model.The design and details of the steel reinforced concrete（SRC） transfer truss,large-span cantilever steel truss of the cinema,membrane structure supported by frame and large-span concrete beam were introduced.The main structure of this project is in good condition after Wenchuan earthquake,proving the efficiency of the design.
