A meso-mechanical model for post-cracking tensile constitutive behavior of steel fiber reinforced concrete

Steel fiber reinforced concrete (SFRC) with hooked-end steel fiber is extensively used in practical structures due to the excellent post-cracking tensile behavior. And the post-cracking tensile stress of SFRC is directly affected by the pullout behavior of the single fiber and the number of fibers that crossed the crack plane. This study presents a theoretical model to estimate the pullout response of the single hooked-end steel fiber, which...
