Due to the large increase of structural glass applications, the lateral-torsional buckling behaviour of glass beams represents a topic of great interest for researchers, as it is often crucial for the design of such members. Although several analytical models and design ap-proaches exist in literature, various aspects complicate their real out-of-plane response, especially in presence of 2 (or more) layer laminated glass sections. In the paper, analytical, numerical and experimental predictions for the elastic critical loads of several PVB and SG laminated glass beams subjected to well-defined temperature and load-time conditions are compared. At the same time, the accuracy of existing analytical formulations for the prediction of their typical load-lateral displacement path is checked with large series of test predictions.
