Abstract
The combined finite/discrete element method is adopted to model the pre-failure and post failure transient dynamics of reinforced concrete structures. For this purpose a novel beam element is introduced in order to increase CPU and RAM efficiency. In this paper the accuracy and reliability of this element is assessed when used in dynamic loading conditions. Experiments, which have already been undertaken at the Swiss Federal Institute of Technology, are used for comparison and validation. The results indicate that the element introduced is capable of accurately modelling inertia and contact effects in pre and post failure dynamics, up to collapse.
