High performance fiber reinforced cement composites (HPFRCC) are highly ductile and are characterized by pseudo strain hardening in tension. It is expected to achieve a high level in structural performance by applying the HPFRCC. However, there are many uncertainties on the influence of the tensile characteristic of HPFRCC to the shear resistance mechanism of structural element applying HPFRCC. Though FEM analysis is an effective engineering tool to analyze the relationship between the materials characteristic and the structure performance of the elements, a robust constitutive model is indispensable for obtaining accurate results. This paper proposes constitutive models based on the basic test results. The proprieties of the model are confirmed based on the comparison between the analytical simulation and the structural test results on the behavior of shear failure. The analytical results using proposed model correspond reasonably well with the experimental results of the HPFRCC structural element.
