| 摘 要： | 为了分析不同锈蚀程度钢筋混凝土梁的力学性能退化规律,采用有限元软件ANSYS数值模拟的方法,用COMBIN39三维非线性弹簧单元来模拟钢筋和混凝土之间的粘结滑移性能,并考虑不同锈蚀状态钢筋的力学性能退化。基于计算结果,对不同锈蚀程度钢筋混凝土梁的荷载-挠度曲线作了探讨,揭示了随钢筋锈蚀率的变化,钢筋和混凝土之间的粘结性能、钢筋混凝土梁的承载力等劣化规律。

| Abstract: | To investigate mechanical property of corroded reinforced concrete beams,COMBIN39 three-dimensional nonlinear spring element is used to simulate the bond-slip relationship between the corroded steel bar and the concrete by finite element ANSYS,and the degradation of mechanical property of the different degree of the corroded reinforcement is also included.Based on the result,the mechanical properties of the reinforced concrete beams were discussed in detail,e.g.the load-deflection curve and bond-slip etc.The mechanical properties degradation rule of the corroded reinforced concrete beams is initially revealed.This study could provide the way for further study of the corroded reinforced concrete beams. |
