Investigation on load bearing capacity of glass panes

Abstract

An experimental study was carried out on BME Department of Construction Materials and Engineering Geology to analyse the bending strength of glass pane. The influence of edge strength of single ply and laminated glass specimens were also investigated. Non heat treated and tempered single ply glass specimens of different thicknesses 6 mm, 12 mm and 19 mm and laminated (2×6 mm, 3×6 mm) glass specimens with constant span of 1.0 m and width of 0.36 m were tested in a four-point bending according to EN 1288-3:2000 [1]. The effect of interlayer material (resin and EVA foil) and the effect of temperature (-20°C, +23°C, +60°C) on the structural behaviour of glass products were also studied. Strains were measured with strain gages in two regions of the surface of the glass pane (Region1 and Region2), see Fig. 1. Surface stresses in two regions and bending strength of glass specimens were determined. © Periodica Polytechnica 2008.
