坑蚀是混凝土钢筋锈蚀的主要形式之一。与钢筋均匀锈蚀相比,钢筋坑蚀具有显著的不确定性和更大的截面损失等特点,对混凝土构件的性能具有一定的影响。借助Monte Carlo模拟,分析了锈蚀钢筋混凝土柱的偏压抗力性能,研究了钢筋坑蚀对混凝土偏压柱承载能力的影响。结果表明,钢筋坑蚀的随机性对柱的可靠性有很大影响,钢筋坑蚀构件承载力的下降速度比均匀锈蚀更快,对柱的耐久性具有潜在危害。

Pitting corrosion is one of the main manners of corrosion in reinforcement concrete(RC).Compared with general corrosion,the process of pitting corrosion shows more uncertainty and greater section loss of reinforcement,which has a significant effect on the performance of component.Based on probability model of pitting corrosion,Monte Carlo simulation method was introduced to analyze the effect of pitting corrosion on the eccentric performance of RC columns.The results indicate that the randomicity of pitting corrosion has a great influence on the reliability of RC columns and the speed of induction of pitting corroded component capacity is much higher than general corrosion,which has a potential hazard on the durability of RC columns.
