ABSTRACT
Abstract A test programme was set up to compare the structural behaviour of seven concrete slabs reinforced with FRP grids to that of a steel reinforced reference slab, in terms of ultimate state (failure aspect and ultimate load) and serviceability behaviour (cracking and deflections). It appears that the design of the slabs is primarily governed by serviceability criteria and that, at the same time, sufficient "deformability" at ultimate is provided. Keywords: FRP grids, concrete slabs, crack appearance, deflection control, serviceability.
