Analytical study for the inelastic behavior and ductility capacity of confined reinforced concrete bridge piers under the
horizontal loading is presented. Simple expressions for the yield curvature of circular and rectangular reinforced concrete
column cross section are presented here, based on moment-curvature analysis. This study includes the material nonlinearity,
tensile, compressive and shear models for cracked concrete and reinforcing steel. The analytical results reveal that the addition
of confinement would enhance the flexural capacity of column.
