Simulation of Highly Ductile Fiber-Reinforced Cement-Based Composite Components Under Cyclic Loading

This research investigates ductile fiber-reinforced cement-based composites (DFRCCs) for new design as well as retrofitting of structures in seismic regions. DFRCC is highly ductile and is characterized by strain-hardening in tension to strains over 3% and by unique cycling loading behavior. In order to accurately predict the structural performance of DFRCC components under cyclic and seismic loading, a robust constitutive model is needed for structural-scale simulations. In this paper, a constitutive model based on total strain is proposed and applied to simulate structural component tests. The model in particular captures DFRCC's unique reversed cyclic loading behavior. Simulation results show that the implemented model is robust and reasonably accurate in simulating DFRCC structural components reinforced with steel and fiber-reinforced polymer bars.
