Design of Multi-Layered Laminated Glass Beams in Lateral-Torsional Buckling

This article proposes a methodology for the structural design of multi-layered glass beams considering lateral-torsional buckling. The basis is the use of two separate effective thicknesses to determine flexural and torsional rigidities, based respectively on the Enhanced Effective Thickness (EET) and sandwich theory. Analytical formulae are then used to calculate the elastic critical bending moment and a design curve is developed based on numerical results. The proposed methodology yields reliable results for the structural design of glass beams in a wide range of current configurations.
