Attaching FRP sheets to the surface of concrete structures for the purpose of preventing deteriorated concrete blocks from potential falling becomes a popular application in Japan. In this application dowel force acts vertically on the FRP sheets and leads to a mix-mode interface debonding. This paper reports summarily a simple test method that has been developed by the authors for evaluating the properties of bond between the FRP and concrete under the dowel action. The interfacial bond mechanisms and corresponding modeling are also presented. As a main focus of this paper, effort has been put on the issue of how to link the interface bond parameters calibrated from the proposed test method to a practical spalling prevention design through analytical modeling.
