Abstract: While the majority of U-shape wrapping (Uwrap) studies have focused on the mechanism of the shear-strengthening effect, very few studies have been devoted to the use of Uwraps as anchorage for longitudinal fiber-reinforced ...

Abstract: This study presents experimental procedures conducted to characterize the bond between concrete and fiber reinforced polymeric laminates. The experimental characterization was aimed at obtaining the softening of the ...

Abstract: In this study, experimental and numerical procedures are proposed to predict the debonding failure of concrete elements strengthened with fiber-reinforced polymers (FRPs). Such debonding is modeled as a damage process, ...

Abstract: In this study, numerical procedures are proposed to predict the structural behavior of concrete members strengthened with fiber-reinforced polymeric (FRP) sheets or plates. The concept of damage band or crack band is ...

Abstract: In this study, numerical models of fiber-reinforced polymer (FRP)-strengthened beams were developed using nonlinear fracture mechanics for the modeling of the concrete-FRP (longitudinal and U-wrap) interfaces. Mode 1, Mode ...

Abstract: The mechanical behavior of the concrete–epoxy bonded interface is of high importance in concrete strengthening and repair systems. This paper presents the effects of cure time, sustained load, and different temperatures ...
