采用面内剪切试验方法,研究冻融循环作用后的CFRP与混凝土的粘结性能。通过试验旨在了解冻融循环作用对界面耐久性能的影响,为寒冷地区结构加固提供理论依据。试验结果表明:冻融循环作用显著影响界面的破坏形态,并且随着冻融次数的增加,界面粘结强度和初始开裂荷载呈降低的趋势。 The in-plane shear test method was used to study the bonding behavior between CFRP and concrete after freeze-thaw cycle. The purpose of this experiment is to understand the effect of freeze-thaw cycles on the durability of the interface and provide a theoretical basis for structural reinforcement in cold regions. The experimental results show that the freeze-thaw cycles significantly affect the failure morphology of the interface, and with the increase of the number of freeze-thaw cycles, the interfacial bond strength and initial cracking load tend to decrease.
