Abstract: Beams made of ultrahigh-performance concrete (UHPC), a fiber-reinforced concrete with high compressive strength and tensile strain-hardening characteristics, exhibit flexural behaviors that are different than those ...

Abstract: Because of their tensile strain-hardening characteristics, ultrahigh-performance concrete (UHPC) materials offer significant advantages in terms of beam shear capacity and postcracking behavior compared to conventional ...

Abstract: 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 ...
