疲劳分析与验算是承受反复荷载作用结构设计的重要内容之一，相应的可靠度为疲劳可靠度。当 结构处于腐蚀环境时，由于腐蚀介质的侵蚀，结构疲劳性能的降低要比静态性能的降低明显。本文研究了腐蚀 环境下钢筋混凝土结构的疲劳可靠度问题，提出了相应的计算方法。计算表明，依赖于钢筋的锈蚀程度，钢筋 混凝土结构的疲劳可靠度有不同程度的下降。
Fatigue analysis and checking are one of the most important parts of the structural design for repeated loading. The corresponding reliability is fatigue reliability. When the structure is in the corrosive environment, the fatigue property of the structure decreases more obviously than the static performance due to erosion of the corrosive medium. In this paper, the fatigue reliability of reinforced concrete structures under corrosive environment is studied, and the corresponding calculation method is put forward. The calculation shows that, depending on the degree of corrosion of steel bars, the fatigue reliability of reinforced concrete structures decreases to some extent.
