摘要：

In order to clarify the distribution of bond stress of CFRP anchorage end, this paper established these mechanical models to study several boundary conditions of the shear behaviors of CFRP reinforced steel structures with end anchorage or not, investigating the effects of end anchorage level on interfacial shear stress. The outcomes indicated that the tensile strain was 0 με if the end of CFRP was unanchored. The tensile strain of the end could reach 50% of the maximum if CFRP was anchored; the interfacial shear stress in the case of end anchorage would decrease by 50% than that unanchored. At the same time the end of CFRP could better coordinate with steel plate, and the shear of interfacial bond stress could be decreased effectively, and then the shear concentration could be eased. In addition, decreasing the number of plies and increasing the adhesive thickness would reduce the shear stress between the bonding interfaces. © 2016, Editorial Board of Journal of Harbin Institute of Technology.
