摘要: 介紹了浙江之江文化中心博物館 100 年設計使用年限的結構設計參數(shù)及抗震性能目標,分析了考慮超大超深地下室開挖卸荷對樁基抗拔承載力的影響,對結構動力特性和溫度作用下的樓板進行了有限元分析。 結果表明,工程結構布置、構件設計參數(shù)及性能目標經(jīng)濟合理。 同時對博物館鋼桁架連廊整體提升施工過程進行了分析,對博物館在罕遇地震作用下的彈塑性時程進行了分析,結果表明,博物館大跨連體結構整體性能及抗震性能良好。

Abstract:The structural design parameters and seismic performance targets of Zhejiang Zhijiang Cultural Center museum for100 years of design service life were introduced, the influence of excavation and unloading of super large and super deepbasement on the uplift bearing capacity of pile foundation was analyzed. The structural dynamic characteristics and floorslabs under temperature were subjected to finite element analysis. The results show that the engineering structure layout,component design parameters and performance objectives are economical and reasonable. At the same time, the overalllifting construction process of the steel truss corridor of the museum was analyzed, and the elastic-plastic time history of themuseum under the action of rare earthquake was analyzed. The results show that the long-span connected structure of themuseum has good integrity and seismic performance.
Keywords:Zhejiang Zhijiang Cultural Center; museum; super large and super deep basement; elastoplastic analysis;longspan connected steel truss
