| 要旨 | The potential of utilizing steel fibres as additional or minimum shear reinforcement in RC beams has been reported widely in the literature. Few studies substantiate on the influencing factors contributing to the shear strength enhancement in steel fibre reinforced concrete beams (SFRC).This study investigated short SFRC beams under bending-shear by optical and Finite Elements analysis methods. It is shown that enhanced crack strain capacity, cracking propagation (stress redistribution) and ductility contribute significantly to the shear strength and deformation improvement in SFRC beams. |
