Original Abstract

The knowledge of values of fracture-mechanical parameters is fundamental for failure numerical modelling of concrete elements. Experimental results of 8 notched-beam concrete specimens subjected to three-point bending are analysed in this papaer. 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, compressive strength and specific fracture energy are recommended as input values of finite element method modelling of concrete beams response.
