摘要
粘结性能退化是锈蚀钢筋混凝土构件力学性能下降的主要原因之一。锈蚀对钢筋与混凝土粘结性能的影响已成为混凝土结构耐久性研究的重要内容。文章全面地介绍了钢筋锈蚀及粘结性能测试的试验方法;系统地回顾与评述了锈蚀引起的粘结强度演化规律、粘结滑移本构关系以及粘结退化对结构承载力的影响等方面的研究进展。
Deterioration of bond strength due to reinforcement corrosion is one of the main causes for losses in mechanical performance of RC members. The effect of corrosion on bond between reinforcement and concrete has become the priority research area for the durability of RC structures. The paper presents test methods for bond behavior evaluation and corrosion tests. The effects of corrosion on bond and bond-slip behavior are systematically summarized. The influence of reduction of bond properties on the strength of RC structures is reviewed, too.
