The current production technology of laminated glass (LG) elements makes the use of stubby sections complex or of little advantage, so that LG slender elements are the most used. To evaluate the structural response of slender elements, it is required to investigate their stability behaviour. The paper deals with the response of slender beams bent about the section strong axis with reference to the possible onset of lateral torsional buckling. The response is strongly dependent on the interlayer capacity to transfer and distribute shear stresses between glass plates. An experimental campaign has been designed to study shear stress transfer mechanisms and failure modes of bent laminated glass beams. Four tests have been performed; specimens consist of 3x12mm thick glass plates for a total height of 300mm and 3.0m span, assembled using PVB or SGP interlayers.
