Abstract:

This study focuses on the steel reinforcing bars found in the reinforced concrete of bridges and which have been shown to be the limiting fatigue component reinforced concrete bridge structures. Researchers studied the effect of externally bonded CFRP on slowing or arresting fatigue crack growth in the steel rebar in a reinforced concrete beam subjected to cyclic loading and service temperature. A unique experimental test was devised to directly measure fatigue crack propagation rates in the tensile steel reinforcement of full-scale reinforced concrete beams with and without CFRP repairs. The results of the tests were then used to determine the material constants in the Paris Law equation.
