“…As cracks develop in the glass, adjacent panes are able to bridge the developing cracks through shear interaction via the polymer interlayer allowing the element to deform and redistribute the load through the adjacent panes. Although the study of the post-breakage performance and robustness of LG components is receiving more and more attention [8,9], much is still unknown about the behaviour in extreme events such as fire.…”

“…A comprehensive state-of-the-art overview is provided in (Martens et al, 2015a;2015b). Since glass is relatively weak in tension but strong in compression, the purpose of adding post-tensioning tendons to a glass beam is firstly to apply a beneficial compressive prestress.…”

In this paper, a Finite-Element (FE) numerical investigation is carried out on laminated glass beams with Carbon Fibre Reinforced Polymer (CFRP) adhesively bonded post-tensioning tendons. Taking advantage of past four-point bending experimental test results available in literature, a refined full 3D FE numerical model is calibrated and validated. A key role is given to a multitude of aspects, including the implementation of damage models for materials as well as the appropriate mechanical interaction between the beam components, in order to properly reproduce the expected effects of post-tensioning as well as the overall bending behavior for the examined structural typology.

“…The concept was also applied in a building project, a glass roof of the spa Badenweiler, Germany (Schober et al 2004). An overview of research and building projects is given in Martens et al (2015). The observed behaviour has confirmed that the applied compressive pre-stress effectively postpones initial cracking of glass beams in bending, while in the post-cracking phase the tendon enables a secondary load-carrying mechanism by taking over the tensile stresses from the glass.…”

This paper presents a study on posttensioned glass beams in a statically indeterminate system. In order to increase the safety of structural glass beams, ductile reinforcement can be added to glass beam sections providing secondary load carrying mechanism in case of glass breakage. In the here investigated post-tensioned system, the reinforcement tendons are additionally pre-tensioned, introducing compressive pre-stress in the beam in order to increase the apparent tensile strength of glass. The system is tested in five-point bending at 23 and 60 • C in order to investigate the basic structural performance and the influence of temperature increase on the initial cracking load and the behaviour of the cracked beam. The benefit of the here investigated statically indeterminate system is a more economical design, i.e. lowering of the bending moment in the span of an equivalent simply supported system by continuing the beam over the central support. The efficiency of the applied system is compared to a reinforced beam system produced in the same batch with similar overall dimensions. The results show an increase of initial cracking load of the post-tensioned beams due to the applied pre-stress and a ductile post-cracking response, reaching high ultimate loads prior to failure. At 60 • C both reinforced and post-tensioned beams show lower initial cracking loads and limited post-cracking ductility but still significant load reserve with ultimate loads well above the initial cracking loads, providing safe failure behaviour.
