Abstract

A combined finite/discrete element model for the pre-failure and post failure transient dynamics of a reinforced concrete structure has been developed. The numerical model uses a simple element already successfully tested for the case of static loading. The accuracy and soundness of this simple element is further assessed under dynamic loading conditions using beam impact experiments undertaken at the Swiss Federal Institute of Technology. The results obtained from these experiments include deflection-time curves for various points along the beam and the deflection pattern for the beam throughout the loading period.
