考虑SSI效应的隔震结构体系振动台模型试验与数值模拟对比研究
|
摘要
基于考虑土-结构相互作用(SSI)效应的隔震结构体系振动台模型试验,以ABAQUS软件为计算平台,考虑土体的非线性特性,建立了将土体一桩基-隔震结构视为共同工作整体的三维有限元模型,对各种试验工况下的地震反应进行了数值模拟计算,并与试验结果进行了对比分析,结果表明:数值模拟和振动台模型试验结果基本一致,两者得到的SSI效应对隔震结构地震反应的影响体现出相似的规律性,印证了数值模型的正确性。
Based on shaking table model tests of isolation structure considering soil-structure interaction(SSI),the ABAQUS software is taken as calculating platform,considering the nonlinear characteristic of soil body,3D finite element model of soil-pile-isolation structure system is established,the seismic responses under different test conditions are simulated numerically,the simulation results and the shaking table test records are compared in detail.The simulation results are basically identical with those of shaking table test,the tested and calculated laws of SSI effects on the isolateion structure are coincident.So that,the analytic model of numerical simulation is proved to be correct.
