[摘要] 舟山市民广场为一门式连体超限高层建筑。对该建筑进行了1:25比例微粒混凝土整体模型的模拟地震振动台试验。采用有限元分析软件ETABS对结构进行了有限元分析，并和试验结果进行了对比分析，研究了结构的动力特性以及在地震作用下的动力响应。研究结果表明，试验结果与理论分析取得了基本一致的结果，起到了相互验证的作用；该结构体系合理，在地震作用下能满足“小震不坏、中震可修、大震不倒”的抗震设防要求。

Abstract: Zhoushan People Square is portal super high-rise building. A 1:25 scale model shaking table test of this building was camed out to study its seismic behavior. The model responses of displacement and dynamic behavior were measured. ETABS was used to analyze the modal structure, and compared with the test results. The result obtained by computational analysis agrees well with the test result. The study results show that the structure can meet the item of no-damage under minor earthquake, repairable under moderate earthquake, and no-collapse under major earthquake, which is required by the Cluna building seisnuc code.
