Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

open access: yesStructural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass
