Comparison between shaking table test and numerical modelling of soil-structure-TMD system

In the shaking table test, to research the effect of SSI on structural control, soil, super structure and TMD structure are combined to four sorts of structure system.Each system is tested on shaking table under the same seismic excitation. Numerical modelling of every structure system is performed by SASSI2000 program for 3D finite element analysis of soilstructure interaction in this paper. In the analysis, the foundation of structure is simulated by 3D solid elements with three translational DOFS per node. The super structure is simulated by beam element and 3D mass matrix. The site consists of semiinfinite viscoelatic horizontal layers on a rigid base. The dynamic nonlinear effects of soils are considered by using equivalent linear method. The comparisons between test results and calculated results show that the test and calculation laws of SSI effects on structural control are coincident. SSI effects have an important influence on structure control. 
