STRUCTURAL BEHAVIOUR OFGLASS/IONOMER LAMINATESD. Callewaert, D. Delincé, J. Belis, R. Van Impetructural glassSPrivate house, Santa FeThe all transparent pavilion, DelftPrivate house, Antwerpaminated glassLIn order to increase the post-failurebehaviour of load-bearing, transparentglass elements, almost always laminatedglass is used. For this, several brittle glasssheets are connected across their entiresurface to a soft interlayer.If the element is subjected to an impact,this material absorbs the impact energy, sonot all glass sheets break. Additionally, theglass fragments remain bonded to thisinterlayer, preventing them to fall down.est programmeTBy doing tests at elevatedtemperatures, the stiffnessthreebehaviour of the laminate at longloading durations is simulated.Because of the complexity ofrealistic loading conditions forstructural glass elements, the testprogramme focuses on twosimplified test setups. One forthree-point bending and one forpure torsion.isco-elastic behaviourVOut of the two different test series,the function between the loadduration and the shear modulusShear modulus GSGP [N/mm²]for the SGP interlayer is deducedthrough analytic models.With the finite element analyses10100(FEA) programme Abaqus©, theseresults will be evaluated. This way,the applicability of the utilized test1programme and the availablecalculation theories is verified.Time [sec]1 10 100Laboratory for Research on Structural Models Technologiepark-Zwijnaarde 904B-9052 Zwijnaarde (Gent)T: +3F: +3Belgium E: DiGlassbridge, RotterdamMaximilianmuseum,AusburgAlte Mensa, DresdenRecently, SentryGlas® Plus (SGP) wasdeveloped as an alternative for the existingsofter interlayer material Polyvinyl Butyral(PVB). With this, also the pre-failurestiffness of the laminate could be increasedsignificantly.Because this is a relatively new, complexvisco-elastic material, there exists onlylittle knowledge of its exact materialproperties.
