This work shows the first results of the flexural behaviour of float glass beams coupled with steel elements. The steel used appropriately when matched to the glass makes it possible to overcome the problem of brittleness, improves the flexural behaviour and increases the strength. The use of steel reinforcement in the glass produces benefits in the elastic phase and allows for a residual resistance in the post-critical phase, allowing to the damaged items to find new equilibrium configurations before arriving to collapse. Two types of elements rein-forced were studied: the first consists of a sheet of glass reinforced with fiber of steel, the second is a beam composed of glass plates arranged vertically reinforced at the intrados. To test the flexural behaviour, both elements were tested to four points bending tests. The results are satisfactory both as regards the increase in strength and stiffness, as well as the residual strength in the post-critical phase. The results were compared with those obtained from differ-ent types of reinforcement: i.e. sheet reinforced with strips of glass fibre and carbon fibre, beams reinforced with pultruded glass fibre.

Abstract
This work shows the first results of the flexural behaviour of float glass beams coupled with steel elements. The steel used appropriately when matched to the glass makes it possible to overcome the problem of brittleness, improves the flexural behaviour and increases the strength. The use of steel reinforcement in the glass produces benefits in the elastic phase and allows for a residual resistance in the post-critical phase, allowing to the damaged items to find new equilibrium configurations before arriving to collapse. Two types of elements rein-forced were studied: the first consists of a sheet of glass reinforced with fiber of steel, the second is a beam composed of glass plates arranged vertically reinforced at the intrados. To test the flexural behaviour, both elements were tested to four points bending tests. The results are satisfactory both as regards the increase in strength and stiffness, as well as the residual strength in the post-critical phase. The results were compared with those obtained from differ-ent types of reinforcement: i.e. sheet reinforced with strips of glass fibre and carbon fibre, beams reinforced with pultruded glass fibre.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
