The constitutive relation of concrete material is one of the key problems in the nonlinear analysis of concrete structure. Much effort has been devoted in the last decade to model the FRC by considering it as a composite material composed of concrete matrix and fibers [15,16,17,18,19].Uniaxial stress–strain behavior is the most fundamental constitutive relationship of the concrete material.
