In this study, cyclic tests are conducted on partially concrete-filled steel bridge piers with the rectangular box sections to examine the applicability of the failure criterion adapted in the present proposal. The criterion is concerned with the average strain over an effective failure length, which is taken as 0.7 times smaller flange width and filled-in concrete height. In the experiment, the flange-web width ratio of the section is examined from 3.0 to 0.5. Comparisons of the tested results and predictions made through the present proposal clarified a necessity of modification of the failure criterion. Based on experimental observations and analytical investigations, it is found that the present proposal can be applied for piers with rectangular sections by introducing an equivalent square section for the rectangular section.
