title = "Evaluation of time and temperature dependent deformation of FRP bonded to concrete",
abstract = "Most of the recent research on the bond characteristics of the concrete-FRP interface involves short-term behavior which may not be indicative of bond behavior following sustained forces on the adhesive joint, particularly in the case of ambient-curing adhesives which can take weeks to reach their full strength capability. The objective of the research effort is to investigate the effects of sustained loads and various temperatures on the bond behavior of FRP sheets bonded to concrete. The approach involves experiments and numerical analysis. The model was parameterized with experiments on the concrete, FRP, interface, and epoxy. Good correlation was seen between the numerical simulations and pull-off experiments. Parametric studies shed light on the influence of temperature, epoxy modulus, and epoxy thickness on the redistribution of interfacial shear stress during sustained loading. This investigation confirms the hypothesis that interfacial stress redistribution can occur due to sustained load and elevated temperature and its effect can be significant.",
