Abstract:Reinforcing bars with a minimum yield strength of 500 MPa (72.5 ksi) are currently in use in Australia. The paper examines the effect of this high strength reinforcement on the bending stiffness of flexural members. The influence of tensile steel ratio, concrete strength and shrinkage of concrete on the bending stiffness is studied using a parametric analysis. It is found that for the same service load the bending stiffness of members with 500 MPa (72.5 ksi) reinforcement varies between 85 and 100 percent of that of members reinforced with 400 MPa (60 ksi) steel depending on tensile steel ratio. Also shrinkage of concrete should be included in the bending stiffness calculations for members with tensile steel ratio less than about 0.008.
