Abstract

High Performance Fiber-Reinforced Cement-based Composites (HPFRCCs) exhibit pseudo-strain hardening behavior in tension and little to no spalling in compression. HPFRCC has been proposed for use in earthquake-and blast-resistant structural design due to its high damage tolerance. Tension-stiffening, bond-slip behavior, and reinforcement fracture failure in reinforced HPFRCC components have been experimentally investigated. Numerical modeling approaches to predict these unique experimental responses have also been developed and are further explored and validated here with a cyclically loaded cantilever beam experiment. Simulation results are able to capture the test strength, stiffness, and hysteretic energy dissipation with reasonable accuracy. With the help of a recently developed bond-slip model for reinforced HPFRCCs, reinforcing strains are also well simulated up to drifts of 6%. At large drifts of 12% when the experiment fails, the simulated steel strains are below the expected failure strain of the reinforcing bar, and two possible causes are discussed.
