Recently,long-period and long-duration time seismic waves have been observed,such as Tokachi-Oki Earthquake and Niigataken-Chuetu Earthquake,and so on.However,seismic performances of structures subjected to long-period seismic waves are not clear.Therefore,in this study,the cyclic load carrying test was carried out in order to investigate the cyclic load bearing capacity of steel bridge piers.Consequently,it is found that the load bearing capacity after the maximum load is decrease about 10%.
