A computer program is developed using Distinct Element for Fracture Analysis (DEF A) of structural media under the dynamic loads. The program has been used for different real failure cases of concrete structures and it is found that more investigation should be done for detennination of fracture physical parameters. In this research one-plane shear specimens have been tested and the physical parameters including cohesion and friction coefficient are detennined. The obtained parameters from the tests and the analytical relations are used in the simulations. The failure mode and crack pattern are very similar in experiments and simulation. The shear strengths obtained from the simulation are well agreed with those from the experiments. Also the distribution of forces and displacements from the numerical analysis are in well agreement with those from the photo- elasticity patterns for such a shear test.
