Glass-Concrete Composite Technology

Exploratory experimental investigations on post-tensioned structural glass beams

“…Together with a compressive force in the (unfractured) top part of the glass beam, an internal moment capacity is generated, which enables the fractured beam to still carry significant load. This concept resembles the reinforced glass beam concept studied earlier by several authors Correia, Valarinho, & Branco, 2011;Cruz & Pequeno, 2008;Freytag, 2004;Kreher & Natterer, 2004;Louter, Belis, Veer, & Lebet, 2012;Ølgaard, Nielsen, & Olesen, 2009;Palumbo, Palumbo, & Mazzucchelli, 2005;Speranzini & Agnetti, 2014;Weller, Meier, & Weimar, 2010). However, the post-tensioned glass beam concept aims at 'active' steel tendons which contribute to the initial fracture strength of the glass beam, as explained earlier, rather than 'passive' reinforcement sections which are mainly activated upon glass fracture only.…”

Development of composite glass beams – A review

“…A second example of composites is the combination of glass and reinforced concrete, investigated by Freytag [26]. As was the case [14], (b) Kreher [15], (c) section for the Palafitte hotel [16], (d) Cruz & Pequeno [17], (e) rectangular section [17], (f) Premrov et al [18], (g) Blyberg [19][20][21], (h) Hulimka & Kozlowski [22] and (i) Kozlowski et al [23].…”

The Load-Bearing Capacity of Timber-Glass Composite I-Beams Made with Polyurethane Adhesives

“…The manner of finishing the glass edges has a significant impact on the bending capacity of composite timber-glass I-beams -this is presented in studies [18,19]. [23,24] and to steel and concrete surfaces [25,26] -this suggests that the failure of the element will appear as a decohesion in the contact zone of the timber and glass or by failure in the adhesive-glass or adhesive-timber zone. Timber parts of the samples were made with structural class C22 fir timber according to [27], and the glass panes were made with float glass (annealed) in accordance with [28].…”
