The study of the structural behavior of some particular glass beams is presented. Two series of beams were constructed, the former alternating glass sheets with sheets of GFRP (Glass Fibre Reinforced Polymers) and the second by coupling glass and glass fibres pultruded profile, with the aim to realize tensile resistant beams and solve the problem of the brightly of the glass and the great dispersion of the tensile strength values. Structural behaviour was studied by subjecting the beams to four-point bending tests. The behaviour of the beams can be clearly seen: all beam specimens show a pre-critical phase characterized by a linear behavior and a post-critical phase represented by a sequence of drops and increases in load. The tests made it possible to evaluate the benefit obtained by applying the reinforcement both in the elastic phase and in the post-critical phase.

Abstract

The study of the structural behavior of some particular glass beams is presented. Two series of beams were constructed, the former alternating glass sheets with sheets of GFRP (Glass Fibre Reinforced Polymers) and the second by coupling glass and glass fibres pultruded profile, with the aim to realize tensile resistant beams and solve the problem of the brightly of the glass and the great dispersion of the tensile strength values. Structural behaviour was studied by subjecting the beams to four-point bending tests. The behaviour of the beams can be clearly seen: all beam specimens show a pre-critical phase characterized by a linear behavior and a post-critical phase represented by a sequence of drops and increases in load. The tests made it possible to evaluate the benefit obtained by applying the reinforcement both in the elastic phase and in the post-critical phase.
