The necessity for realistic constitutive models that represent ECC's behavior under load grows as research in ECC progresses from material creation to structural applications. Constitutive models of ECC can be used to simulate structural responses when paired with the finite element approach. These simulations are helpful in gaining a better understanding of how ECC's unique features, such as tensile ductility and fracture width controlling, may be translated into enhanced structural performance. In this work, phenomenological models for 1D are presented which includes the constitutive models for plain ECC under tension compression, as well as reinforced beams behavior under bending. The models given lay the groundwork for more growth in this subject, which is desperately needed. as result, monotonic loading applications for specific structures showed their variety, weaknesses were also found. These include the tendency to predict a tougher and stronger structural reaction than experimental findings. This is because the multiple cracks can only deform in the opening mode, but not in the sliding mode.
