Abstract:

To investigate the seismic performance of reinforced concrete (RC) hollow rectangular bridge columns retrofitted with carbon fiber reinforced polymer (CFRP), cyclic testing of eight RC specimens was performed under constant axial load and uniaxial bending. The failure characteristic, flexural ductility, dissipated energy and hysteretic behavior of RC rectangular hollow bridge columns constraint with CFRP are analyzed, and a simplified effective lateral confined model of CFRP is proposed by considering effective strength coefficient and area distribution ratio of CFRP hoops. The hysteretic behavior and its influence parameters of hollow rectangular bridge columns retrofitted with CFRP are studied based on fiber element model using the OpenSees program. The results indicate that the ductility and dissipated energy of the rectangular hollow bridge columns with CFRP are improved greatly, but the load capacity is less influenced. The proposed simplified analytical method can be well used to analyze the lateral force and deformation hysteretic behavior of hollow rectangular bridge columns retrofitted with CFRP. ©, 2015, Editorial Office of China Civil Engineering Journal.
