Abstract
The authors propose a new approach for fracture problems in the field of concrete engineering by the discrete element method (DEM). The DEM can be applied to a series of behavior of materials from continuous to discontinuous state. The DEM is suited to simulate fracture behavior such as crack, crush, slide, separation etc. of media. In this paper, the simulation analyses by the DEM are performed for uniaxial compression test, splitting tensile test of concrete cylinder and impact test on reinforced concrete slabs, and also some analytical investigations are made on the fracture characteristics of concrete structures.
