Regarding the circular-section steel bridge pier (steel pipe column) designed by the seismic coefficient method, a quasi-static cyclic loading test and a pseudo-dynamic test using reduced-scale test specimens of the same details were conducted . And using the pseudo-dynamic test results as the comparison, the effectiveness of the seismic resistance capacity evaluation method was investigated, based on the information obtained from a cyclic loading test . The investigation results show that the dynamic analysis results using the restoring force model (two-parameter model) obtained from the hysteresis loop of the cyclic loading test agree well with the results of the pseudo-dynamic test . On the other hand, it was confirmed that the seismic resistance capacity based on property of energy conservation using the hysteresis loop envelope curve results in underestimation
