Residual Behavior of Shear-Repaired Concrete Beams Using CFRP Sheets Subjected to Elevated High Temperatures
This paper presents the residual behavior of unreinforced concrete beams repaired with carbon fiber-reinforced polymer (CFRP) sheets in shear subjected to elevated temperatures up to 200°C. An experimental program is conducted to examine the effects of high-temperature exposure on the response of constitutive materials, adhesive–concrete interface, and shear repaired beams. All test beams are notched to represent various levels of shear deficiency. A predictive modeling approach is proposed based on classical laminate theory. Elevated temperatures influence the capacity and interfacial characteristics of the repaired beams. Temperature effects, however, are not significantly correlated with the formation of diagonal tension cracks (shear crack) and their propagation rate. Shear resistance of the CFRP is found to be independent of high-temperature exposure because of the load-resisting mechanism associated with crack-plane strains and shear-failure angle.
