Abstract

 Recently, high acceleration and high frequency near-field vertical ground motions were recorded at several sites. The extreme vertical ground motions can induce high frequency varying axial force which develop even tensile force in reinforced concrete bridge columns. Cyclic loading experiments of RC columns were conducted to clarify the seismic performance of RC bridge columns under near-field vertical ground motions. It is shown that core concrete is crushed extensively due to varying axial force after longitudinal bars buckle.
