A large scale shaking table test has been carried out to investigate the amplification effect of ground motion in homogeneous and complex heterogeneous sites. After that, a Fourier transform, time frequency analysis method and subsection time-frequency analysis method are combined to analyze the experimental data. By comparing the experimental results,, the peak of the time curve of the ground motion will be gradually enlarged with the increase of the height of the site when the local vibration propagates i...
