摘要
在总结近年来国内外大量研究成果的基础上,对受腐蚀钢筋混凝土结构的力学性能进行了论述,同时针对海洋环境腐蚀的特点,提出了海洋环境下结构力学性能方面应该研究的课题。为海洋腐蚀环境下钢筋混凝土结构的耐久性设计和使用寿命评估提供参考。
Based on the results of a lot of researches on corroded reinforced concrete structures in the world in recent years, this paper summarizes and discusses the mechanical properties of concrete members which have suffered from different degrees of reinforcement corrosion, including mode of failures, flexural loading capacity and ductility, bonding properties between reinforcement and concrete, influences of cracking and loading on corrosion as well as hysteretic characteristics. For the reinforced concrete structures deteriorated seriously in marine exposure conditions, problems related to corrosion are analyzed and further research tasks in marine environment are put forward. The paper aims at providing a reference for the durability design and evaluation of service life of reinforced concrete structures in marine environment.
