Firstly, soil's damping coefficients are focused. Optimum coefficients are conducted for solving the seismic response of piers. And then, in terms how to use Rayleigh's damping, little consideration is given. As a result, if severe response of bridge piers would like to be calculated, it is necessary that the modes which pier is greatly deformed are selected. Finally, numerical results given this study are compared with the results from analytical model not considering soil-structure interaction.}, pages = {465--474}, title = {鋼製橋脚ー地盤系の地震応答解析における減衰マトリクスに関する一考察}, volume = {49A}, year = {2003} }
