Experimental Study on Shear Behavior of Concrete Beam Reinforced With 500 MPa Stirrup

Abstract:

Twelve concrete beams reinforced with 500 MPa stirrups were tested and some relevant factors including shear behaviors, crack width and deflections were analyzed. Based on analysis results, some corresponding suggestions to “Code for design of concrete structures”(GB 50010—2010) were put forward. It is shown that the code can precisely predict the shear capacity of highstrength concrete beams. In serviceability limit states, the design value of shear strength cannot exceed 80% of that in the code. Moreover, the effects of shear deformation should be considered when caculating the deflection of the member subjected to shear deformation with the code.
