组合寿命准则分析混凝土结构的耐久性与可靠度

摘要

The influence of carbonization and steel corrosion on durability life of structures is analyzed and studied in case of concrete’s carboniza-tion in this paper, meanwhile, the effect of carbonization and corrosion on the origin and development of concrete crack is also researched. The method is put forward to analyze concrete structure’ s durability with combined life criterion. Finally, the analysis method of structure’ s durability is discussed from the angle of time variant reliability.%以混凝土碳化为例，分析和研究碳化与钢筋锈蚀对于结构耐久性寿命的影响，以及碳化和锈蚀对混凝土裂缝的产生以及发展的影响，提出了以组合寿命准则分析混凝土结构耐久性寿命的方法，最后，又从时变可靠度的角度探讨了结构耐久性的分析方法。
