Abstract:
Although considerable researches have been conducted on strengthening RC structures using FRP method during past years, a few researches have been reported on RC arch or curved structures strengthened by FRP. In this study, behavior of RC arches strengthened by FRP strips is investigated. The behavior of strengthened RC arches under gravitational load is analyzed using finite elements method. The arches are modeled by appropriate software in order to evaluate the behavior. The structural behavior of arches is more complicated. So, the estimation of the effect of strengthening using FRP technique on such structures is hard in comparison with traditional RC beams. In this study, the effect of strengthening arches using FRP laminate was carried out using ABAQUS software. Arches with various spans and heights were modeled and the maximum improvement in load carrying capacity was about 30%. As it was expected, using FRP plates increased the strength of RC arch structures and also the ductility, but in some models the displacement correspond to peak load was decreased
