［摘要］為研究武漢中心結(jié)構(gòu)的抗震性能，按照1∶40的縮尺比例制作了結(jié)構(gòu)縮尺模型并進(jìn)行了振動臺試驗(yàn)。根據(jù)振動臺試驗(yàn)結(jié)果，采用ETABS和ABAQUS軟件針對試驗(yàn)縮尺模型建立有限元模型，進(jìn)行了包括模態(tài)分析和動力時(shí)程分析在內(nèi)的數(shù)值模擬研究。將有限元模型的周期、振型、加速度反應(yīng)和位移反應(yīng)等結(jié)果與試驗(yàn)實(shí)測結(jié)果做比較，并探討了有限元模型構(gòu)件應(yīng)變與試驗(yàn)實(shí)測應(yīng)變的規(guī)律。研究結(jié)果顯示，有限元模型參數(shù)取值準(zhǔn)確，數(shù)值模擬分析結(jié)果與振動臺試驗(yàn)結(jié)果基本一致，具有相似的規(guī)律性，同時(shí)也驗(yàn)證了試驗(yàn)結(jié)果的可靠性。

Abstract: In order to study the seismic behavior of Wuhan Center, a 1/40 scale structural model was made and tested on a shaking table. Based on the test results, numerical simulation study of modal analysis and dynamic response analysis were done by using two finite element models which were built by ETABS and ABAQUS. The simulation results and shaking table results including natural vibration period, vibrational modes, acceleration responses and displacement responses were compared. The strain of critical members of finite element models and test model were also discussed. Study results indicate that the parameters of finite element model are rational, and the numerical simulation results are basically identical with the test results. So the simulation results can prove the reliability of test results.

Keywords: shaking table test; seismic behavior; high-rise building; numerical simulation; finite element method
