The soil-structure interaction(SSI) analysis is essential to soil site where shear wave velocity is less than 1,050 m/sec and soil nonlinear characteristics for this kind of soil site have to be considered in SSI analysis. In order to consider soil nonlinear characteristics in the SSI analysis, simple and reliable soil nonlinear evaluation technique with seismic recorded data at downhole array is proposed in this study. The SSI analysis is carried out in order to prove the reliability of the proposed evaluation technique with Hualien large scale seismic test(HLSST) site in Taiwan. The analytical result are compared with Hualien earthquake recorded data and the analytical results with SHAKE program which is prevailed at present. As a result, the proposed evaluation technique shows a good agreement with both the Hualien earthquake recorded data and the analytical result with SHAKE program and the reliability and usefulness are confirmed.
