［摘要］ 新津水互動中心為一宣傳水文化的博物館建筑。主體結(jié)構(gòu)主要是由二維混凝土板殼組成的復(fù)雜混凝土空間結(jié)構(gòu)，結(jié)構(gòu)形式罕見，而且建筑中存在多處大跨結(jié)構(gòu)：端部30m的大懸挑、中部38m的大跨門拱、劇場上30m跨的混凝土折板屋蓋等。為滿足建筑要求，重點解決了奇異空間結(jié)構(gòu)的建模分析、鋼筋混凝土二維構(gòu)件多軸受力條件下的截面設(shè)計、復(fù)雜結(jié)構(gòu)的抗震設(shè)計、超長結(jié)構(gòu)的無縫設(shè)計以及異形鋼筋混凝土結(jié)構(gòu)的構(gòu)造設(shè)計等難點。

Abstract: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.
Keywords:complex space concrete structure; structural analysis; shell element design; detailing design
