N2 - The behavior of a reinforced concrete dapped-end beam under dynamic load is expected to vary from its behavior under static load. Although, many studies have been conducted on the performance of reinforced concrete rectangular beams under different types of dynamic loading, but in-depth investigations on the preformation of half- joints or dapped-end beams under impact loading are limited. Due to complexity and resource requirements for experimental study on half-joints, often numerical simulations are preferred. This study presents details of advanced finite element modelling of dapped end beams under impact loads to achieve a better understanding of their performance. This study includes modelling techniques using different constitutive material models for concrete to highlight the suitability of various concrete models to demonstrate the behavior of beams with half-joints. Verification results of the modelled dapped-end beam has been presented along with results showing behavior of modelled beam under different impact loads.
