Behaviour of fibre-reinforced concrete beams on grade

The University of New Brunswick's Geotechnical Research Group has an ongoing research programme investigating the behaviour of steel-fibre-reinforced concrete (SFRC) beams on grade. The development of a state-of-the-art behavioural model of SFRC slabs on grade requires that numerous intermediate steps be investigated. With this approach, testing of beams representing two-dimensional components of SFRC slabs has been completed. The purpose of this experimental programme was to obtain pre- and post-cracking response data for beams on grade subjected to repetitive loads and to compare the observed response of these beams with monotonically loaded beams on grade.
