The analytical solution to the post-peak slope of the stress-strain curve of a uniaxially compressive concrete specimen subjected to single shear failure in the form of the shear band exhibiting linear strain-softening behavior beyond the peak stress was generalized as the nonlinear case.Prior to the peak stress,the Scott model was adopted to describe the nonlinear constitutive relation.The nonlinear strain-softening constitutive relation was back-calculated from the derived post-peak slope of the shortest ...
