［摘要］杭州市科技館是具有兩個通高玻璃幕墻的共享空間、豐富多變的建筑邊際曲線，傳力路徑復(fù)雜的大跨度空間結(jié)構(gòu)與多層結(jié)構(gòu)共存的組合結(jié)構(gòu)體系。對杭州市科技館采用鋼結(jié)構(gòu)方案和鋼筋混凝土結(jié)構(gòu)方案進(jìn)行比較。采用MIDAS設(shè)計(jì)軟件對兩種方案進(jìn)行了多遇地震彈性分析及罕遇地震作用下靜力彈塑性（Pushover）分析，針對性能曲線、層間位移角、塑性鉸分布等結(jié)構(gòu)性能進(jìn)行對比分析，并綜合考慮施工可行性及投資。研究表明，鋼結(jié)構(gòu)方案抗震性能明顯優(yōu)于鋼筋混凝土結(jié)構(gòu)方案，且施工方便、施工周期短。經(jīng)綜合對比，最終確定采用鋼結(jié)構(gòu)方案。

Abstract: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 elasticplastic 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.
Keywords:structural scheme; elastic-plastic analysis; earthquake-resistance performance
