Flexural behaviour of concrete slabs reinforced with steel sheet

This is a report on tests carried out on concrete slabs reinforced with bonded steel sheet, where flexural stiffness and ultimate capacity were improved versus conventional r. c. slabs. In the case of sheet metal, which has biaxial strength properties, the steel is far better utilized than in that of the uniaxial reinforcing bars, hence the slab structure is more economical. Fire- and corrosion protection is provided by a 10 mm coating of fire-shield plaster (or some other insulating agent).
