Based on the fundamental test data and the mesoscopic approach, a rigid body spring model is developed for simulation of the behavior of large aggregate concrete subjected to uniaxial or multiaxial load. Firstly, the concrete is treated as a three-phase inhomogeneous system; random aggregate model for fully-graded concrete is used to form the aggregate distribution. Then, based on the rigid body spring discrete element model, a procedure for mesoscopic study behaviour of large aggregate concrete under the two-dimensional stress state is given. At last, the comparison of numerical and experimental results shows that this method could effectively describe the failure behavior of large aggregate concrete under various plane stress state.
