Prediction of cracking behavior and deformation of reinforced concrete is a complex problem, including reinforced concrete that can still bear tensile stress after cracking due to the bond between reinforcement and surrounding concrete, termed the tension stiffening effect. This research aims to determine the tension stiffening of reinforced HVFA-SCC at various tensile reinforcement ratios. In this tension-stiffening analysis, shrinkage and creep effects are taken away. The data used in the analysis were obtained from beams tested with four loading points. The tests were conducted on 6 reinforced HVFA-SCC beams, and 6 Normal Concrete (NC) beams with dimensions of 150 x 250 x 2000 mm, with tensile reinforcement ratios of 0.61%, 1.10%, and 1.55%. The analysis shows that the effect of creep on shrinkage is so tiny that it can be ignored in the calculation. In addition, shrinkage is very influential in concrete calculations because the value of the maximum tension stiffening stress due to shrinkage increases by 1.39%, and the ultimate tension stiffening stress increases by 66.65% from the initial tension stiffening stress. In addition, the greater the tensile reinforcement ratio in concrete, the smaller the effect of tension stiffening stress.
