| 摘要： | Reinforced concrete (RC) structures are designed in such a way that flexural yielding precedes bond failure, in order to ensure the ductile behavior of members. When subject to cyclic loading including seismic loads, brittle bond failure may occur due to bond deterioration at the interface between concrete and longitudinal reinforcement. To prevent the brittle failure of RC members in which flexural yielding occurs first, this study proposes a model to predict the bond stress-slip relationship and evaluate the ductility of members based on the test results of RC members that experience bond failure after flexural yielding. The variables of the proposed model are lateral loading patterns, confinement conditions of longitudinal reinforcement, and yield strength of lateral confining reinforcement. The reliability of the proposed model was verified by comparing the test results for RC members to the analytical results. The proposed model provided outstanding predictions for the bond stress-slip relationship and ductility of RC members. |
