Finite Element Modeling of Brickwork Panels Strengthened with Fiber Reinforced Concrete layer

Several researches have been carried out on seismic behavior and retrofitting of unreinforced masonry (URM) walls. Using an external retrofitting surface layer is the most popular strengthening technique for URM walls. Recently, using fiber reinforced concrete (FRC) overlay as a strengthening techni...
