浙江之江文化中心博物馆结构设计

Structural design of Zhejiang Zhijiang Cultural Center museum

介绍了浙江之江文化中心博物馆100年设计使用年限的结构设计参数及抗震性能目标,分析了考虑超大超深地下室开挖卸荷对桩基抗拔承载力的影响,对结构动力特性和温度作用下的楼板进行了有限元分析。结果表明,工程结构布置、构件设计参数及性能目标经济合理。同时对博物馆钢桁架连廊整体提升施工过程进行了分析,对博物馆在罕遇地震作用下的弹塑性时程进行了分析,结果表明,博物馆大跨连体结构整体性能及抗震性能良好。

The structural design parameters and seismic performance targets of Zhejiang Zhijiang Cultural Center museum for 100 years of design service life were introduced,the influence of excavation and unloading of super large and super deep basement on the uplift bearing capacity of pile foundation was analyzed.The structural dynamic characteristics and floor slabs 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 overall lifting construction process of the steel truss corridor of the museum was analyzed,and the elastic-plastic time history of the museum under the action of rare earthquake was analyzed.The results show that the long-span connected structure of the museum has good integrity and seismic performance.
