Comparison between shaking table test results and numerical simulation of isolated structure system considering SSI

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.
