Simulation of Flexural Behavior of Reinforced Concrete Beams under Impact Loading

Abstract:

This paper focuses on the numerical simulation of the flexural behavior of reinforced concrete beams under impact loading by the LS-DYNA finite element code. An enhanced version of the Concrete Damage Model Release 3 (K&C) was used for the concrete materials and a Plastic Kinematic Model was adopted for steel reinforcement, both material models used parameters to cope with the effects of strain rate. The simulation also took the bond between concrete and steel bar into consideration, and its behavior model was based on high strain rate experimental results. The simulation of the mid span drop tests, both with and without bond consideration, were compared to experimental results to investigate the influence of bond consideration and the reliability of the overall simulation model. Compared with experimental results, the calculated mid-span deflections with the bond model agreed much better than those without the bond model, and a simplified formulation was drawn from the trend on deformation depending on the impact velocity.
