In order to find deformation capacity of reinforced concrete bridge piers under earthquake, cyclic horizontal loading tests were carried on the specimens of bridge piers for which span ratio, tensile reinforcement ratio, web reinforcement ratio and axial compressive stress have been modified, and the effect due to these factors against deformation capacity has been identified.
Furthermore, a study was made on the method to obtain ductilities for quantitative evaluation of deformation capacity of the reinforced concrete bridge piers, and a method capable of calculating thereof relatively accurately was proposed.
