Abstract: Over the past ten years, the use of steel fibres as the only reinforcement within structural concrete slabs has been developed and is now in routine use for applications such as industrial suspended floor slabs resting on a grid of piles, spanning from 3 m to 5 m each way and with a span to depth ratio of 15.
The structural use of steel fibre has been further investigated including the use of 100kg/m³ or more of steel fibres. This has been considered as the only concrete reinforcement needed in case of fully elevated suspended slabs spanning from 5 m to 8 m each way, with a span to depth ratio of 30.
A 200 mm thick suspended, fully elevated concrete slab of 335m², supported on columns spanning three times 6m x 6m each way, has been built as a full scale testing slab. This article reviews the testing results under uniformly distributed service loads and point loads to final rupture. Comparison is made to laboratory testing using various shapes and sizes of specimens.
