In this study, it is examined at first the difference between the frequency domain analysis and the time domain analysis. As a result, it was confirmed that frequency domain equivalent linear method is able to be applied to dynamic response analysis of steel structure, when the input earthquake motion is small. On the contrary, RC structure, with larger mass and higher stiffness, is subject to the larger effects of soil-structure interaction, and the results of the different modeling don’t coincide well with each other. It needs more extensive meshes or sophisticated boundary conditions for such structure. Moreover, when extensive foundation soils become nonlinear due to strong earthquakes such that all nonlinear domains are not contained in FEM model, usual viscous boundary conditions cannot absorb outgoing wave well. The efficient PML boundary is proposed for linear and nonlinear FEM analysis. The analytical results are compared with those of extensive meshes and these results agree well. It shows good performances of these boundary conditions.
