Description
Summary:•The main features of numerical model for analysis of RC structures are presented.•Numerical model is based on combined finite–discrete element method (FEM/DEM).•Computational aspects related to modelling of progressive fracturing are discussed.•Progressive collapse due to impact and intensive seismic excitation is presented. This paper reviews several computational aspects of the combined finite–discrete element method related to the modelling of plane reinforced concrete progressive fracturing. It discusses especially the ability of the presented numerical model, extended with a new model of reinforcing bar, to simulate the behaviour of the reinforced concrete structure through the entire failure mechanism from the continuum to the discontinuum. It also presents similar topics, including the tracing of the progressive collapse due to impact loading and the intensive seismic excitation.
