Inelastic behaviour and ductility capacity of circular hollow reinforced concrete bridge piers under earthquake

The purpose of this study was to investigate the inelastic behaviour and ductility capacity of circular hollow reinforced concrete bridge piers based on various design parameters. The ultimate strength and ductility of these bridge piers varied with the amount and arrangement of lateral reinforcement, the ratio of the inside to outside diameter of the column sections, the axial load ratio and longitudinal steel percentage. A total of eight solid...
