Triaxial Constitutive Law for Ultra-High-Performance Concrete and Other Fiber-Reinforced Cementitious Materials
This paper presents a triaxial constitutive model for fiber-reinforced cementitious materials (FRCM), with an emphasis on ultra-high-performance concrete (UHPC). The model accounts for the multiaxial stress-strain behavior of the cementitious matrix and the fiber stress-versus-slip response. The distributed cracking due to the presence of fibers, the fiber confinement effect on the compressive response of the composite material, and the effect of fiber orientation on the material response are also accounted for in the proposed formulation. The new material model is calibrated and validated using material test data on UHPC. The capability of the model to allow the simulation of structural components is verified through the analysis of structural components made of UHPC.
