Abstract
High-performance fiber reinforced cement composites (HPFRCC) are highly ductile and characterized by pseudo strain hardening in tension. High-level in structural performance through the application of HPFRCC is expected. However, many uncertainties remain regarding the influence of the tensile characteristic of HPFRCC on the shear resistance mechanism of structural elements utilizing HPFRCC. Though FEM analysis is an effective engineering tool to analyze the relationship between the material characteristics and the structural performance of elements, a robust constitutive model is indispensable for obtaining accurate results. This paper proposes constitutive models based on basic test results. The proprieties of the model are confirmed based on a comparison between the analytical simulation and the structural test results for shear failure behavior. The analytical results using the proposed model match reasonably well the experimental results of HPFRCC structural elements.
