| Abstract: | According to the regression analysis for large amounts of experimental results,the influences of shear span to depth ratio,concrete strength,steel fiber content and longitudinal reinforcement ratio on the shear strength of steel fiber reinforced concrete beams without web reinforcement are concluded.The differences in the effect among these factors are presented.The analysis indicates that the shear span ratio exerts the most significant affection to the shear strength of steel fiber reinforced concrete beams without web reinforcement.A regression formula in suggested for predicting the ultimate shear strength of steel fiber erinforced concrete beams without web reinforcement. |
