In this study, meso-scale (mm-cm scale) modelling approach is adopted to simulate the behaviour of plain concrete beam under 3-point bending. At meso-level, concrete is assumed as either a twophase or a three-phase composite material (mortar, aggregate and/or interfacial transition zone- ITZ). In this tudy, first the aggregates are generated and placed in the concrete domain with prescribed randomness. The remaining space in the concrete domain is then filled with mortar. However, in three phase model, ITZ of finite thickness surrounding the aggregates is assumed to exist. In this study, three geometrically similar beam specimens with and without notch have been considered. The simulated load-crack mouth opening displacement (CMOD) is then validated with the corresponding experimental data. A convergence study of peak load with different specimens in terms of randomness in aggregates generation and placement has been studied. © 2020 IABSE Congress, Christchurch 2020: Resilient Technologies for Sustainable Infrastructure - Proceedings.
