Abstract

Research efforts have recently been made to simulate the performance of reinforced high- performancefiber-reinforcedcementcomposites(HPFRCCs)athighlevelsofdeformation. Although constitutive models for HPFRCCs have been developed, selecting appropriate mechanical properties of HPFRCCsinsimulationsremainsacritical aspect to predicting component response in large-scale structures. Additionally, fiber orientation and specimen size are known to significantly impact the tensile and flexural response of HPFRCCs. This paper investigates the simulated performance of re- inforced HPFRCC components using tensile properties obtained through various testing and casting methods which result in different fiber orientation. An emphasis is placed on predicting reinforced HPFRCCperformance at high levels of deformation, and specifically reinforcement fracture, using total-strain based material models. Recommendationsaremadeforselectingappropriatetest-methods and casting-methods for characterization specimens that can improve simulated performance of rein- forced HPFRCCcomponents.
