Abstract: To investigate the seismic performance of partially concrete-filled steel bridge piers under actual earthquake excitations, cyclic static loading tests, single-and bi- directional hybrid loading tests were conducted using total 12 test specimens with circular cross-section. The height of the filled concrete is up to the 25% and 50% of the pier height. The earthquake acceleration data recorded on the medium ground in 1995 Kobe Earthquake were used in the hybrid tests. From the experimental results it was observed that the strength and ductility of the steel columns with concrete filled decreased considerably under bi-directional hybrid loading in comparison with those under single-directional hybrid loading. The filled-in concrete was effective in improving the seismic behavior of steel bridge piers, especially for case of sufficient length of concrete filled.
