Original Abstract

The knowledge of values of fracture-mechanical parameters is fundamental for failure numerical modelling of concrete elements. Experimental results of 6 notched-beam concrete specimens subjected to three-point bending are used here. Effective crack model is applied to determine fracture-mechanical parameters. The results of the paper are mean values and variability of selected fracture-mechanical parameters. Values of modulus of elasticity and specific fracture energy are recommended as input values of finite element method modelling of anchor-concrete response.
