成都新津水互动中心结构设计

Structural design of Xinjin Water Museum in Chengdu

新津水互动中心为一宣传水文化的博物馆建筑。主体结构主要是由二维混凝土板壳组成的复杂混凝土空间结构,结构形式罕见,而且建筑中存在多处大跨结构:端部30m的大悬挑、中部38m的大跨门拱、剧场上30m跨的混凝土折板屋盖等。为满足建筑要求,重点解决了奇异空间结构的建模分析、钢筋混凝土二维构件多轴受力条件下的截面设计、复杂结构的抗震设计、超长结构的无缝设计以及异形钢筋混凝土结构的构造设计等难点。

Xinjin Water Museum is a building which aims to exhibit the water culture.The structure,with an irregular shape,is a complex space structure mainly composed of 2D concrete shell element.Furthermore,there are some long-span structural parts in the building,such as cantilever structure with the length of 30m at the end,arch structure with the span of 38m in the middle,and the folded RC plate roof of the theater with the span of 30m.To satisfy the architectural requirement,the structural analysis of the complex space structure and design of shell element under multi-dimensional force were paid more attention to and solved.In addition,seismic design and detailing design of such a complex space RC structure and super-long structure without any movement joints were discussed.
