| Research Abstract |
It is thought that the strong motions caused by huge ocean-trench earthquakes are long-period and long-duration time seismic waves. However, seismic performances of structures subjected to long-duration time seismic waves are not clear. In seismic design codes in Japan, there are no specific descriptions concerned with the seismic performance of structure subjected to long-duration time waves. Therefore, in this study, cyclic load carrying tests and a pseudo-dynamic test were 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% due to cyclic loading over 10times and that the cyclic loading history over 100 times are caused.
