Abstract

To investigate the restoring force characteristics of T-joints between PVC-CFRP confined concrete columns and RC ring beams, eleven exterior joint specimens under quasi-static loading were tested. The experimental results showed that the enlarged ring beam joints could effectively connect the PVC-CFRP confined concrete columns and RC beams, and the joint specimens showed favorable seismic performance. On the basis of the experimental study, the material constitutive relations were reasonably selected, the fiber model method was adopted, the nonlinear analysis program was compiled, and the quasi-static tests of the exterior joint specimens were simulated numerically. The model predicted results agreed well with the experimental data. Based on the numerical model verified by experiments, the effects of concrete strength, height of ring beam, longitudinal reinforcement ratio of beam, column diameter and yield strength of longitudinal reinforcement on skeleton curves were analyzed, and reasonable design suggestions were proposed. The numerical simulation results showed that when the concrete strength of the ring beam joint increased from 20 MPa to 60 MPa, the peak bending moment increased by 13.7%, while the ultimate displacement decreased by 8.0%. As the longitudinal reinforcement ratio of beam increased from 2% to 5%, the peak bending moment increased by 26.3%, while the ultimate displacement decreased by 19.9%. As the yield strength of beam longitudinal reinforcement increased from 400 MPa to 600 MPa, the peak bending moment increased by 56.3%, while the ultimate curvature decreased by 17.9%. When the height of ring beam increased from 350 mm to 450 mm, the peak bending moment showed little influence, while the ultimate displacement decreased by 11.0%. When the column diameter increased from 200 mm to 300 mm, the peak load increased by 56.3%, and the ultimate displacement increased by 28.5%.
