Abstract
This paper investigates pullout behavior of embedded deformed bars in concrete under coupled transverse shear arising at a crack of reinforced concrete. It was experimentally proven that the pullout capacity, which reaches yield of steel section at a crack under uniaxial tension, does not come up with full yielding of the critical section where the axial stress gets maximum, but the ultimate limit state is reached not at the RC crack plane but inside location in which induced curvature by shear slip of crack takes place. It is concluded under higher reinforcement ratio and/or flatter planes of concrete joints, coupling of pullout and transverse shear of steel at a crack cannot be ignored in structural analysis.
