Originální abstrakt

Selected results of extensive fracture testing of steel fibre reinforced concrete (developed in industry for the production of prefabricated concrete elements) after different period of hardening are presented in the paper. Experiments were performed on notched specimens in a three-point bending test configuration. The fracture parameters were evaluated using three models/approaches: double-K fracture model, effective crack length method, and work-of-fracture method. The obtained parameters can be used to quantify the structural resistance against crack initiation and propagation – or the brittleness and toughness/ductility of the structural members – as well as for the comparison of the studied or developed cement based composites or the structural members of buildings. They can be also employed for the definition of the material models for deterministic or stochastic simulation of the quasi-brittle/ductile response of cement based composites/members using Stochastic Finite Element Method model with nonlinear fracture mechanics principles implemented – this approach can help to the optimal design of developed prefabricated concrete elements.
