| 摘 要： | 鉴于现在广泛应用的拉拔式试验结果不能反映实际受弯构件中钢筋与混凝土的粘结性能,设计了梁式试件来研究钢筋与混凝土之间粘结性能.采用半干法的钢筋通电快速锈蚀法对钢筋进行锈蚀.在此基础上,对锈蚀钢筋的混凝土梁受力各阶段特征点的粘结应力及滑移值进行试验测定,拟合出粘结滑移曲线及锈蚀对粘结性能影响曲线.基于试验数据,提出了锈蚀率及锈胀裂缝宽度对钢筋与混凝土粘结强度影响系数的建议表达式. |
| 关 键 词： | 梁式试验 锈蚀钢筋 滑移曲线 粘结性能 |

| Abstract: | In view of the fact that pull-out test can not reflect the bond behavior of practical flexural member between concrete and corroded steel bar,the device of beam model experiment was designed to study the bond behavior between concrete and corroded steel bar.The semidry accelerated corrosion method with current was used simultaneously.On the basis,the bond strength and free-end slip of the corrosion reinforced concrete beam under various loading stages were measured by experiment,and nonlinear fitting curves... |
