In this study, on the basis of the static loading test results of concrete specimens reinforced by BFRP grid and PCM, a series of fatigue tests with different loading levels were conducted on interfaces between BFRP grid and concrete to investigate the fatigue behavior of BFRP grid-concrete interfaces. The test results indicate that with high loading level, the fatigue failure mode of interface is interfacial peeling failure while it transforms to the fatigue fracture of the BFRP grid under low loading level. The fatigue life ( )根据不同的破坏模式，得到了BFRP网格-混凝土界面的分段拟合曲线，并指出了两种破坏模式的临界点。进一步揭示了两种失效模式下不同阶段界面的相对滑移演化规律，并研究了界面应变随疲劳次数增加的规律。阐述了界面有效结合长度与疲劳时间的关系。SN - 1687-8434 UR - https://doi.org/10.1155/2020/9624154 DO - 10.1155/2020/9624154 JF - Advances in Materials Science and Engineering PB - Hindawi KW - ER -
