摘要
在考虑锈蚀引起的钢筋横截面损失和粘结强度下降的前提下,利用非线性弹簧单元模拟锈蚀钢筋与混凝土之间的粘结滑移性能,建立了锈蚀钢筋混凝土梁的有限元分析模型。对锈蚀钢筋混凝土梁承载力进行仿真分析,讨论了钢筋截面损失和锈蚀率对钢筋混凝土梁承载力的影响。
The section loss of steal bars and degradation of bond intensity were taken into consideration in this study in order to establish the finite element model of corroded reinforced concrete beam through simulating the bond slip behavior between steel bar and reinforced concrete based on nonlinear spring element. The force-bearing capacity of corroded reinforced concrete beam was numerically investigated and the effects of section loss of steel bars and corrosion rate on structural force-bearing capacity were also discussed.
