Abstract
This paper shows the potential of adhesively-bonded thin Glass Fibre Reinforced Polymer (GFRP) strips to reinforce annealed glass as a means of ensuring adequate ductility and load resistance in glass structures. Using experimental results of double-layer annealed glass beams reinforced with an adhesively-bonded thin GFRP strip, the paper shows that the combination of the GFRP strip and the top (i.e. compression) glass sheet can ensure a notable load resistance in the beam after the bottom (i.e. tension) glass sheet has cracked. The reinforced beams showed ‘displacement ductility index’, which was defined as the ratio of the additional midspan deflection after reaching the peak load to the midspan deflection at the peak load, greater than 400%. In the latter half of the paper, it is shown that the stress concentration geometries such as glass around holes can be reinforced with adhesively-bonded GFRP strips. The reinforced glass resisted higher loads compared to unreinforced glass and managed to carry load even after microcracks have formed in glass.
