| 摘 要： | 本文对锈蚀钢筋混凝土简支架进行了试验研究，其试验结果表明梁的承载能力和延性有明显退化现象，其破坏形态向脆性破坏转化。利用钢筋混凝土结构有限元方法和钢筋与粘结性能的退化数学模型，对不同锈蚀量的钢筋混凝土梁进行了分析，并对锈蚀钢筋混凝土梁的结构性能退化机理进行了研究。

| Abstract: | Corroded reinforced concrete beam tests have been carried out to study the influence of rein-forcing bar corrosion on the deterioration of structural behavior in beams. Test results show that the deteioration of the bearing capacity and ductility of beam are obvious and the failure mode of the beam turns to brittle failures. The beams at different corrosion levels have been analyzed using the finite elememt method, the influence of corrosion on mechanical behavior of steel bar and bond being also analyzed. Furthermore, the mechanism of deterioration of the structural behavior has been studied from test and analytical results as well. |
