Abstract: 
The paper reports results of physical tests on three different ribbed slab typologies, extensively utilized in Italy in the 60’s. The use of lightweight ribbed one-way Reinforced Concrete slabs is quite common in Italy and southern Europe, especially in residential buildings where they allow for a reduced self weight in comparison with a whole concrete section having similar bearing capacity, resulting in a lower seismic action. As many of those structures nowadays do not satisfy the requirements of the new building codes, both at ultimate (ULS) and service (SLE) conditions, the behavior of a slab before or after strengthening was compared toward the evaluation of the efficiency of the strengthening technique, in terms of increase in the post-cracking stiffness, ductility and bearing capacity. The proposed technique results a valuable and promising methodology for an effective strengthening of ribbed slabs.
