Abstract: Fourteen high strength reinforced RPC beams were tested to study the shear performance
of them. The influence of shear span ratio, steel fiber content, stirrup ratio, reinforcement ratio
and reinforcement strength was considered. The cracks and failure mode of the beams were
observed. The concrete strain and load-deflection curves were analyzed. The change
regulation of the beam’s cracking load, shear strength and ductility was drawn. The results
show that: In certain range, the shear capacity can be improved by the increase of steel fiber
content, stirrup ratio, reinforcement ratio and reinforcement strength and reduced by the
increase of shear span ratio. The inclination angle of cracks and failure mode of the beams are
mainly influenced by shear span ratio. The optimal content of steel fiber should be between
2%-3%. The shear ductility can be improved obviously by the increase of stirrup ratio in a
certain range.
