Research on Constitutive Law of UHPFRC Used in Numerical Simulation
This paper presents compressive and tensile constitutive law of UHPFRC used in numerical simulation. UHPFRC exhibits different constitutive law from normal and high strength concrete. A multi-directional fixed crack criterion that considers tensile strain hardening is defined to describe tensile behavior, and Drucker-Prager criterion with an associate d flow rule is adopted in the compressive region. The comparison of numerical results with experimental results indicates a good agreement.
