A shortcoming of the method of adding epoxy-bonded steel plates to the tension face of concrete girders is the danger of corrosion at the epoxy-steel interface, which adversely affects the bond strength. An effective way of eliminating the corrosion problem is to replace steel plates with corrosion-resistant synthetic materials such as fiber composites. In addition to corrosion resistance, many fiber composites have tensile and fatigue strengths that exceed those of steel. Five beams were used to test the static strength of concrete beams strengthened with epoxy-bonded GFRP plates. Strengthening concrete beams with epoxy bonded GFRP plates appears to be a feasible way of increasing the load carrying capacity of existing bridges.
