| Abstract;This paper investigated appropriate model-establishment methods for applying a bi-linear model and a two-parameter model to a circular-section steel bridge pier(steel pipe column), respectively, regarding the restoring force characteristics used for nonlinear dynamic analysis. By this investigation, we obtained a solution which approximates the results of a pseudo-dynamic test by establishing, in the case of the bi-linear model, yield point coordinates approximating the hysteresis absorption energy in a quasi-static cyclic loading test and, in the case of the two-parameter model, by applying the type of the restoring force model, which takes into account the effect of the strain hardening due to cyclic loading.
