Based on the improved Z-W-T model, the fitting error of the stress-strain curve of recycled concrete under impact load under different steel fiber content and different strain rate was only within 10%, which proved that the model has better fitting ability and can accurately describe the mechanical behavior of steel fiber recycled concrete under dynamic impact. The numerical simulation conducted using ANSYS/LS-DYNA offered a superior representation of the dynamic behavior and performance characteristics of concrete which proved the tendency of internal stress of recycled and the effectiveness and accuracy of impact simulation.
