[摘要] 舟山市民廣場(chǎng)為一門(mén)式連體超限高層建筑。對(duì)該建筑進(jìn)行了1:25比例微?；炷琳w模型的模擬地震振動(dòng)臺(tái)試驗(yàn)。采用有限元分析軟件ETABS對(duì)結(jié)構(gòu)進(jìn)行了有限元分析，并和試驗(yàn)結(jié)果進(jìn)行了對(duì)比分析，研究了結(jié)構(gòu)的動(dòng)力特性以及在地震作用下的動(dòng)力響應(yīng)。研究結(jié)果表明，試驗(yàn)結(jié)果與理論分析取得了基本一致的結(jié)果，起到了相互驗(yàn)證的作用；該結(jié)構(gòu)體系合理，在地震作用下能滿足“小震不壞、中震可修、大震不倒”的抗震設(shè)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.
Keywords: portal building; super tall-building; shaking table test; similitude relationship; fiute element analysis
