【摘要】：以结构满足规范规定最低耐久性要求为前提,对港口工程钢筋混凝土结构的钢筋锈蚀率、承载力可靠度、纵向裂缝宽度和刚度退化系数进行了概率分析。结果表明,随着结构使用年限的增加,上述指标均有不同程度的降低。分析结果为制定合理的结构耐久性极限状态及建立相应设计方法提供了依据。
[Abstract]:Based on the premise that the structure meets the minimum durability requirement stipulated in the code, the probability analysis of the corrosion rate, the reliability of bearing capacity, the width of longitudinal crack and the coefficient of stiffness degradation of reinforced concrete structures in port engineering are carried out. The results show that with the increase of the service life of the structure, the above indexes are decreased to some extent. The results provide a basis for the establishment of reasonable limit state of durability and the establishment of corresponding design methods.
