Bond Properties of Additional Anchorage Schemes for a CFRP Plate-Concrete Externally Bonded System
This paper presents experimental results that highlight the complex bond behavior in a CFRP plate-concrete externally bonded system with an additional anchor. The use of the anchor is aimed at achieving three goals, which are transverse strengthening, stiffness improvement, and load distribution. The experimental results from 30 direct shear tests, divided into three groups, are reported based on the failure mode, the load-displacement relationship, the strain distribution, and the local bond stress-slip relationship. Two new simple models are proposed based on the existing bond-slip model and experimental observations. A numerical analysis is performed based on the proposed models. These models not only agree well with the experimental results but also correctly predict the relationship between the bond length and anchorage strength. This research contributes information to the experimental database and for prediction methods to aid in the future development of design recommendations for externally bonded systems with an additional anchor.
