【摘要】：以結(jié)構(gòu)滿足規(guī)范規(guī)定最低耐久性要求為前提,對港口工程鋼筋混凝土結(jié)構(gòu)的鋼筋銹蝕率、承載力可靠度、縱向裂縫寬度和剛度退化系數(shù)進(jìn)行了概率分析。結(jié)果表明,隨著結(jié)構(gòu)使用年限的增加,上述指標(biāo)均有不同程度的降低。分析結(jié)果為制定合理的結(jié)構(gòu)耐久性極限狀態(tài)及建立相應(yīng)設(shè)計(jì)方法提供了依據(jù)。
[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.
