摘要
钢筋混凝土结构可能会同时受到多种腐蚀介质的侵蚀。本文给出了钢筋混凝土结构常见的几种腐蚀失效模式。考虑了失效模式间的相关性对结构整体可靠度的影响,用系统可靠度方法分析了多种腐蚀因素作用下钢筋混凝土结构的可靠度并给出了算例。该分析方法计算简便,可以作为多种腐蚀介质环境下结构可靠度分析的参考方法。
The reliability for the RC structures under corrosive effects is studied in the paper. It is the system reliability method that is used for analysis. It is found that the RC structures sometimes are invaded by several corrosive media. The failure modes of RC structures induce by corrosion factors are discussed. It includes the carbonization of steel bar, the corrosion of rebar induced by chloride ions, and the sulfate attack of concrete. The influence of the correlation of failure modes to the reliability of RC structures is investigated. It is an example that is made for illustrating.
