“…Structural glass beams and plates find primary applications in buildings in the form of stiffeners and structural components able to carry on loads. Such beams usually act as stiffeners and intermediate supports for roof and façade panels, based on mechanical or adhesive joints able to provide a certain structural interaction between them . In the case of glass panels, a wide range of possible geometrical configurations and restraint solutions can be found in practice, involving the use of aluminum or steel frameworks and cable‐nets, timber frames, adhesives, or metal point fixings only …”

Shape-Memory Alloys (SMAs) are a class of metal materials that exhibit two outstanding properties, the superelastic and the shape-memory effects. Taking advantage of these properties, several SMA actuator wires and plates have been proposed over the last years in robotic, automotive, and biomedical engineering. In this paper, the feasibility of a novel design concept of SMA-reinforced laminated glass panels is proposed, based on an adaptive embedded system built up of SMA wires. Glass panels used as cladding walls in facades have in fact typically high size-to-thickness ratios, hence, major restrictions in design are represented by prevention of glass failure and large deflections. It is expected, based on the current investigation, that useful design recommendations can be derived for this novel design concept

“…The objective of the study (Schärer 2015) was the development of a simple design method in order to pro-vide structural engineers in practice a safe and economic design of glass beams with lateral restraints. As demonstrated in previous works (Luible 2004;Bedon et al 2015) a design approach based on buckling design curves, a common design practice in structural steel design, may also be applied for glass. However, due to different material behaviour and also imperfections, which have a significant influence on the load bearing capacity, steel buckling curves may not be directly applied for structural glass elements.…”

“…In practice, especially when glass beams are applied in frameless glass facades, the glass beams are connected to the front glazing by mechanical fixings, like clamps, or glued with structural silicone. The effect of continuous elastic sealant joints on the LTB behaviour of glass beam was assessed in a theoretical research in (Bedon et al 2015). Based on previous research work and parametric FE simulations, analytical solutions are suggested for the estimation of the elastic critical buckling moment of monolithic glass beams under various loading conditions.…”

There is a growing trend in steel glass facades to maximize the transparency of buildings with structural glass elements e.g. beams, columns, and stiffeners. A relatively new way is the use of glass beams in order to stiffen large glass curtain walls. Although the material glass is a material that is able to resist very high compression stresses, structural glass elements tend to fail because of instability due to their high slenderness. In the past years lateral torsional buckling of glass beams has been studied in many research works. The studies were limited to the fundamental situation of a simple beam without lateral restraint. However, in practice glass beams in glass curtain walls are fixed over the whole length to the front glazing panels by means of structural silicon joints or mechanical fixings. The load carrying behaviour of beams with lateral restraints is different compared to beams with a free lateral displacement. In this work, experimental and theoretical investigations on the lateral torsional buckling of monolithic and laminated glass beams with lateral restraint have been conducted. The objectives were to investigate the load carrying behaviour and to study possible design methods for stability-critical lateral supported glass beams. Finite element simulations were carried out and compared to experimental tests on real size glass beams made of monolithic and laminated glass. The design concept is based on well-known design con

“…The fatigue strength of rectangular glass specimen subjected to cyclic‐torsion depends on the ratio of specimen width to specimen thickness . A few studies on torsional buckling of LG were reported in the cited literature . Belis and Luible evaluated an existing model for lateral torsional buckling analysis of the LG‐PVB beams using simulations and the experiments.…”

Cyclic fatigue strength (CFS) of laminated glasses (LGs) with different interlayers and their different nominal thicknesses were compared. The effect of interlayer thickness, cyclic bending fatigue load, and interlayer type on CFS is clearly observed from this brief study. It was found that the LG‐PVB has comparatively lower CFS than LG‐EVA. There is an increment in CFS with an increment in critical interlayer thickness (significantly for an increment from 0.38 to 0.76 mm) in both LG‐EVA (prominent) and LG‐PVB. The maximum deformation at failure load at the corresponding number of cycles is obtained using the finite element model. The strain‐life relations for LG samples were established and shown by surface plots. The results of finite element analysis previously established fracture models were used to explain the fracture patterns of the LG samples. The conclusions of the study are useful for the selection of LG in fatigue prone LG structures.
