Abstract

The aim of this work is to investigate the fracture process of concrete under various boundary conditions. Although numerous concrete fracture tests have been reported, showing the failure behavior of concrete, their evaluation is ambiguous due to the limitations of specimen size and experimental conditions. Therefore, it is necessary to use simulation models to better understand the fracture process. This is done herein by using a three-dimensional lattice model to simulate the failure behavior of concrete under different loading conditions ranging from uniaxial compression, tension, splitting, three point bending to shear by using a single set of input parameter. In addition, several influence factors including boundary condition and slenderness are also taken into consideration to give more detailed information about the fracture process of concrete.
