摘要：
Steel fiber reinforced self-compacting high performance concrete (SFRSCHPC) shows significant advantages in workability and toughness. Shear strength and shear toughness are important parameters for members mechanical analysis. In this paper, modified compact shear test are carried out, the research results on shear behavior of SFRSCHPC, including shear-slip curve, shear strength, the first crack slip, and the shear toughness, were presented. Steel fiber can obviously improve the shear strength, and significantly increase shear toughness; the shear strength and shear toughness increase with the increment of fiber dosage. The modified compact shear test and proposal method can be used to evaluate the shear strength and shear toughness.
