ABSTRACT
ABSTRACT: As the current transport infrastructure grows older, there is a rising need to find an easy and effective way to rehabilitate existing steel bridges and to extent their fatigue life. As corrosion is almost always present on old bridges, the stress increases close to the corrosion pits and can lead to the creation of fatigue cracks. One of the most promising new method of repair is the use of Carbon Fiber Reinforced Polymers (CFRP). The paper describes the results of the numerical analysis of the deteriorated steel elements reinforced with CFRP. Several numerical models in Abaqus software were created with different level of corrosion. The difference in the stress level and distribution in the specimens with and without the CFRP will be analyzed. Even a small decrease can significantly extend the remaining fatigue life. The results will serve as a basis for further experimental research works.
