000021583 520__ $$2eng$$aThe methods of damping selection are different, therefore there will be a great difference in the results of time domain analysis and frequency domain analysis. The results of time domain analysis and frequency domain equivalent linear analysis are compared by single-layered soil columns with different thicknesses and multi-layered soil column under different input ground motions. How to evaluate Rayleigh damping coefficient is also discussed. The results show that the selection of different target frequency influencing viscous damping coefficient is the main reason leading to different results in time domain analysis. Hysteretic damping can be used more exactly in time domain site response analysis. To reduce the differences of the results of time domain analysis and frequency domain analysis, the full Rayleigh damping formulation and the first and third natural frequency can be employed.
