Temperature dependent load bearing capacity of laminated glass panes

Abstract

An experimental programme with numerous single and laminated glass specimens was carried out to study the temperature dependent behaviour of laminated glasses. The difference of load bearing capacities between the laminate manufactured from ordinary float (laminated glass) or tempered glass layers (safety laminated glass) were also studied in four-point bending. When glass laminate fractures, the interlayer can keep the fragments in place. Different types of interlayer materials, both resin and foil (type EVA) were studied in safety and non safety laminated glass specimens. Glasses are used not only in the interior but also in exterior places. Therefore, the effect of temperature of -20^o C, +23\r C and +60^o C were investigated on bending characteristics of glasses. The main influencing factors on the load bearing capacity and bending characteristics of the glass specimens were investigated e.g. tempering, laminating and temperature.
