- Abstract:
- This paper presents an experimental study of shear behavior of simply supported HSC beams reinforced with high-strength stirrups under monotonic concentrated loading. Six specimens with 150×300 mm square cross section were tested. The effects of three variables such as the stirrup ratio, stirrup yield strength and average confining stress are studied. Based on test results, the shear behavior of HSC beams with high-strength stirrups was evaluated. Combined with other test results, shear strength measured in test are compared with the values calculated according to the expressions proposed in this paper and in Code for design of concrete structures of China (GB 50010-2002). The study concludes that shear capacity is sparingly estimated by the Code for design of concrete structures of China (GB 50010-2002) when the average confining stress below 3MPa, but it is emphasis on insecurity when the average confining stress exceeds 3MPa. The empirical equation proposed in this paper for predicting the shear strength of HSC beams with high-strength stirrups is appropriate.
