The seismic behavior of concrete-filled circular steel bridge piers was studied by testing four large scale models which were subjected to a constant axial load in addition to a cyclic lateral load. It was found that concrete-filled circular steel bridge piers had high ductility and energy dissipation capacity. Based on the hysteretic force-displacement, the hysteretic behavior of strength reduction was analyzed. Based on the axial strain and the circumferential strain, the plastic area and the strain feature of steel tube were analyzed. According to two different constitutive models of concrete-filled steel tube, the skeleton curve of moment-curvature and force-displacement were calculated and compared with testing data.

Buckling Behavior

<p>In Japan, many steel structures were constructed during the period of the high economic miracle, and they are now more than 50 years old and are aging. Corrosion has been confirmed at corners and the boundary of concrete-wrapped concrete in steel piers. It was found that corrosion damage at the corner of steel piers causes a decrease of seismic performance in our previous investigations that carried out seismic response analysis. Subsequently, in this study, the effect of corrosion damage at the near ground edge of steel bridge piers with a rectangular cross-section was investigated in detail on the buckling behaviour and seismic performance of structures. As a result, it is found that the buckling at the base causes a decrease in load bearing performance compared to the buckling in the entire panel. It is necessary to properly maintain to prevent buckling at the base caused by corrosion.</p>
