A SFRC Slab For A Residential Building In Erba, Italy

In Erba (Italy), a two-stories family house has been recently completed. The building is characterized by a Steel Fibre Reinforced Concrete (SFRC) slab used to optimize the presence of conventional steel bars. The paper describes the design philosophy based on the approach proposed in the new Model Code 2010. Some preliminary experimental tests that have driven the design choices are then described. The control of the fibre content at the fresh state and the mechanical strength of the SFRC material are discussed. The reliability of an analytical model used for the design of the SFRC slab is evaluated. The curing procedures adopted to limit the cracking phenomena are described. The advantages of a SFRC slab compared to traditional solutions and an experimental campaign on structural beams carried out after the SFRC slab casting are finally discussed.
