The application of FEM/DEM method in analysis of RC beam-column joints
One of very interesting problem in civil engineering applications is reinforced concrete beam-column joints subjected to monotonic and cyclic load. Predicting of the behaviour of reinforced concrete beam-column joints under monotonic and cyclic loading imposes the need to develop numerical model which will be able to include effects of the behaviour of reinforced concrete structures due to dynamic action in linear elastic stage, crack initiation and propagation, energy dissipation mechanisms due to n on linear effects, inertial effects due to motion, contact impact and finally to attain state of the rest that is a consequence of energy dissipation mechanisms in the system. It is possible to include all previously mentioned effects with the finite- discrete element method (FEM/DEM). In this paper, a robust numerical model of concrete reinforcement, which is based on approximation of the experimental curves for behaviour of the concrete and steel in crack, is aimed to predict the behaviour of reinforced concrete beam-column joints subjected to monotonic and cyclic load. Cracking of the structure is enabled by discrete model of cracks where the cyclic behaviour of concrete and steel was implemented. The development of the cracks is analyzed for mid and end RC beam-column joints.
