【摘要】 本文针对国内最大单体隔震建筑建立了SAP2000三维分析模型,并进行了动力特性的理论分析;现场对实际建筑进行了平移振动、扭转振动、垂直振动和平面内弯曲4个方面的脉动测试。利用工程振动反演理论分析了该结构的固有频率、振型、阻尼等动力特性,将实测结构动力特性与理论分析结果进行比较,详细分析实测结果与理论结果差别的原因,并据此对理论模型进行修正,为今后类似结构的设计积累了资料。更多还原

【Abstract】 The 3D analysis model of the largest isolation structures in China is established using SAP2000 and the dynamic behavior of the structure is analyzed theoretically. The translational, torsional, vertical and bend in plane of the structure is tested on spot via micro-tremor method. Engineering vibration inversion theory is used to analyze the natural frequency, mode shape, damping ratio of the structure. Based on the comparison of test and theoretical analyzing results by which we figured out the reason of difference, necessary amendments have been added into the model, this makes preparation for future structure design.更多还原
