摘要
杭州市科技馆是具有两个通高玻璃幕墙的共享空间、丰富多变的建筑边际曲线,传力路径复杂的大跨度空间结构与多层结构共存的组合结构体系。对杭州市科技馆采用钢结构方案和钢筋混凝土结构方案进行比较。采用MIDAS设计软件对两种方案进行了多遇地震弹性分析及罕遇地震作用下静力弹塑性(Pushover)分析,针对性能曲线、层间位移角、塑性铰分布等结构性能进行对比分析,并综合考虑施工可行性及投资。研究表明,钢结构方案抗震性能明显优于钢筋混凝土结构方案,且施工方便、施工周期短。经综合对比,最终确定采用钢结构方案。
The structural steel scheme for Hangzhou Science and Technology Museum is compared with the reinforced concrete scheme. The elastic normal seismic analysis and the static elastic-plastic ultimate seismic analysis （Pushover analysis） are conducted by using MIDAS software, to compare and analyze the performance curve, the inter-formational displacement, and the distribution of plastic hinge, as well as the construction feasibility and the investment are estimated. As shown in the research, the structural steel scheme has more advantages than the reinforced concrete scheme, and the construction of steel structure is convenient with short period of time. To be comprehensively compared, the structural steel scheme is selected.
