Abstract

The wedge splitting method according Tschegg has been used to determine the fracture-mechanical values for cubes (e.g. 150 × 150 × 150 mm3) under uniaxial (tension) and biaxial (compression + orthogonal tension) loading. The steel-fibre-reinforced concrete had fibre lengths of 15 to 60 mm and a volume content of 0.5 to 1%.
The fracture behaviour and the influence of the fibre length and the fibre content on the fracture parameters can be explained qualitatively using a very simple model. Finally, some aspects relating to the biaxial fracture testing in steel-fibre-reinforced concrete which are of interest to engineers are discussed.
