Ductility of Rectangular Reinforced Concrete Bridge Columns with Moderate Confinement
The research examined the ductility and behavior of rectangular reinforced concrete bridge columns with moderate confinement. The research comprised experimental and analytical investigation of the response of such columns when subjected to lateral loading. Four half-scaled rectangular bridge columns were built and tested. The geometrical dimensions and the amount of longitudinal reinforcement were kept the same for all specimens. Each specimen was tested under constant axial load while subjected to lateral load reversals with increasing drift levels. The lateral loading was quasi-static and uniaxial in the column strong direction. Two parameters were varied: the transverse steel reinforcement amount and the axial load level. In the analytical study, several existing models pertaining to the concrete stress-strain relationship and the plastic hinge length were utilized and compared.
