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
