摘　　要：对已有的8根锈蚀钢筋混凝土梁进行有限元建模和分析,得到钢筋腐蚀率为0%、5.0%和10.0%的钢筋混凝土梁的荷载-跨中挠度曲线。研究结果表明,较高的锈蚀率会对RC梁的刚度、承载能力以及破坏形式等产生不利影响,且通过和破坏试验的对比分析可以看出,通过有限元软件ANSYS能较准确地模拟锈蚀RC组件的力学行为。研究成果可在一定程度上对耐久性损伤结构的加固有参考意义。Based on the finite element modeling and analysis of 8 collected corroded reinforced concrete beams,the load-mid-span deflection curve of reinforced concrete beams with reinforcement corrosion rates of 0%,5.0%and 10.0%are obtained.The results show that the higher corrosion rate has an adverse impact on the stiffness,bearing capacity and failure mode of RC beams,and that through the comparative analysis with the failure test,it can be seen that the mechanical behavior of corroded RC components can be accurately simulated by the finite element software ANSYS.This research results can have reference significance for the reinforcement of durable damage structures to a certain extent.
