Original Abstract
This paper deals with the application of the effective crack model to a chevron-notched core-based concrete specimen loaded in a three-point bending fracture test configuration. Selected concrete spec-imens damaged by high-temperature loading were analysed along with reference ones from the same type of concrete but with no temperature exposure. The effective crack length was assessed for each fracture test by a parametric study using a model based on the finite element method. The calculated values of effective fracture toughness are compared with fracture toughness values determined by the linear elastic fracture mechanics approach
