Abstract
An assessment of the reliability of reinforced concrete beams with corroded reinforcement was proposed based on the computation of
the reliability index. The corrosion was induced by chlorides provided from de-icing salts or marine breeze. Models for chloride diffusion
and corrosion kinetics were chosen depending on the availability of consistent statistical data, and as well as to represent the physical
phenomena realistically. The statistical distributions were specified from a wide review of previous studies for environmental parameters
(surface chloride concentration or flux, coefficient of diffusion, corrosion current density) and a

摘要
评估的可靠性，钢筋混凝土梁的钢筋腐蚀的基础上，提出的计算
可靠性指标。腐蚀是由氯化物提供除冰盐或海洋微风。模型的氯离子扩散
和腐蚀动力学被选为根据现有的统计数据相一致，并以及代表物理
现实的现象。统计指定的分布从广泛的审查以往的研究环境参数
（表面氯离子浓度或流量，扩散系数，腐蚀电流密度） ，也为几何参数和
力学性能的材料。各种设计规格占设计相应的光束不同
预计程度的攻击性的环境和可能的混凝土开裂。时间依赖的可靠性评价
考虑到以往生存期的结构。结果表明，影响可靠性的接触条件，
混凝土质量和设计的选择根据法国的设计规则。
