EXPERIMENTAL STUDY OF REINFORCED CONCRETE BRIDGE PIERS SUBJECTED TO BI-DIRECTIONAL QUASI-STATIC LOADING

Abstract

This research aims to determine the effect of loading pattern on the damage of a reinforced concrete bridge column. Five specimens were tested with uni-directional or bi-directional cyclic loading patterns combined with a uniform axial load. From the test results, the theoretical plastic hinge zone length was calculated considering the yield penetration effect and the energy dissipated by the specimens was obtained.
