Abstract: 
Full scale tests on five one-way slabs with steel fibre concrete have been tested at the Technical University of Eindhoven. The slabs were produced using a tunnel forming technique, which is a well known technique for residential applications. The walls and slabs have been executed with only steel fibre concrete. All five spans tested showed a quite ductile behaviour resulting from a significant moment redistribution of moments together with a multiple cracking pattern under sagging moments. The deviations on the load bearing capacity between the five spans tested are significantly smaller than the deviations in the characterisation test EN14651. EN14651 test method shows a deviation that is typical to the test method only and not to the real behaviour of the structure as tested. The first crack experimental loading intensity in all 5 spans occurred at more than 250 % of the standard housing service loading intensity in The Netherlands (2,25kN/m²). The ultimate loading experimental intensity in all 5 spans occurred at more than 450 % of the standard housing service loading intensity in The Netherlands (2,25kN/m²). The Model Code draft 2010 predicts well the behaviour of the structure in bending, as long as the standard deviations in the characterisation tests are in the range 10-20%.
