Analysis of the Interface Performance of Concrete Elements Reinforced with Synthethic, Natural and Steel FRP Materials

Abstract

The use of fiber-reinforced composite materials, as externally bonded reinforcement, for strengthening existing concrete structures, has gained an increasing success, as shown by the wide available literature on this topic and the extensive practical applications worldwide. However, as well known, some key aspects need further investigations like as the bond performance between the reinforcement and substrate. At the same time, the need of standard test to evaluate the bond performance as well as the assessment of law of general validity increases in the designer area. In the present work single face shear tests were carried out on concrete elements reinforced with different types of FRP reinforcement and considering both FRP sheet applied with hand-lay-up technique and FRP pre-cured laminate. The experimental results are analyzed and discussed.
