Incremental dynamic analysis of RC walls based on FEM/DEM method

In this paper an incremental dynamic analysis of reinforced concrete walls under seismic load based on a combined finite-discrete element method (FEM/DEM) is presented. Fragmentation that may occur during and after seismic loading cannot be modelled by the continuum methods. Predicting of the behaviour of reinforced concrete structures under seismic load 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 non 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 FEM/DEM method. The performance of the FEM/DEM method is presented through incremental dynamic analysis of reinforced concrete wall.
