Bending behavior of structural glass laminated with different interlayers

Abstract

Experimental results on the bending strength of structural laminated glass are presented. Three different interlayer laminates were used: polyvinyl butyric (PVB), ethylene vinyl acetate (EVA), DuPont SentryGlas Plus (SGP), and a 6-mm-thick tempered soda-lime-silica glass. Four-point bending tests up to failure were carried out on test specimens according to the EN 1288-3 standard and deflections at the midspan of the specimens and the sliding displacement between their two structural glass sheets with different types of interlayer laminates were measured. A comparison between experimental results for the resistances of glass composite panels with various interlayers and monolithic glass sheets is presented too.
