要旨 This paper discusses the effects of dowel force acting on FRP sheets on the shear bond force transfer capacity of FRP sheet-concrete interface. It is found that the dowel force affects the initiation of interface peeling significantly. Moreover, dowel deformation ability of FRP sheets in concrete beams strengthended with FRP sheets decreases greatly with increasing the pullout force in FRP sheets. However, ultimate interface shear bond force capacity is negliigibly affected by the dowel deformation if a sufficient anchorage length is provided and if the dowel deformation is limited under asuggested value.
