Originální abstrakt

The paper presents results of the determination of mechanical fracture parameters for specified concrete types after different hardening periods. The concretes subjected to investigation are used in industry for the production of prefabricated concrete elements. Mechanical fracture parameters were determined with the cooperation of two laboratories (the University of Natural Resources and Life Sciences, Vienna, Austria and Brno University of Technology, Czech Republic) using two different test configurations - wedge splitting and three-point bending. In addition, identification was performed based on artificial neural networks in combination with stochastic analysis using the whole experimentally obtained load-deflection curve. The obtained mechanical fracture parameters can be used to quantify the structural resistance against crack initiation and propagation (or the brittleness and toughness of the structural members). Simultaneously, they can be employed for the simulation of the quasi-brittle random behavior of beams/structures made of cement-based composites, including material uncertainties required for reliability analysis (statistical characteristics of fracture-mechanical parameters, including statistical correlations).
