| 摘 要： | 考虑到氯盐对钢筋锈蚀会引起钢筋横截面损失和粘结强度下降，硫酸盐对混凝土侵蚀会引起混凝土强度改变，因此，建立受腐蚀钢筋混凝土（ reinforced concrete ，RC）梁的有限元分析模型，利用大型有限元ANSYS分析软件，对腐蚀梁的受力性能进行模拟分析，模拟结果与实验结果吻合，说明采用非线性有限元方法分析锈蚀梁受力性能正确有效。

| Abstract: | Considering the section area loss and the decrease of bonding strength of steel bars caused by the cor -rosion of chlorides and strength change of concrete by erosion of sulfates , the finite element analysis of the corro-ded reinforced concrete beam is established .To simulate the bearing capacity of the beam , analysis is compared with the results of the experiment .It turns out that it is reliable and accurate to use nonlinear finite element anal-ysis for the corroded reinforced concrete beam . |
