| 摘要： | This study proposes a model to predict bond stress-slip behavior by conducting tests on RC members that experience splitting bond failure when subject to cyclic loading such as seismic loads. The specimens had a shear span-to-depth ratio of 1.8, and splitting bond failure was induced by applying antisymmetric bending moment. The main variable of the experiment was the confinement of the longitudinal reinforcement; high-strength transverse reinforcement was used in the specimens to evaluate the bond performance of the RC members in relation to the yield strength of the transverse reinforcement. Based on the experimental results, the confinement conditions of the longitudinal reinforcement and the yield strength of the transverse reinforcement were selected as main variables in the prediction model for bond stressslip behavior. The proposed model also considered changes in bond stiffness and bond deterioration caused by loading history. The effectiveness of the proposed model was evaluated through a comparison of the analytical results and experimental results. The model provided highly precise predictions of the bond stress-slip behavior of specimens. |
