Glass beam-like elements are largely used in building structures in the form of primary load-bearing members. Large studies recently focused on specific structural behaviours under various loading and boundary conditions. Lateral-torsional buckling (LTB) of beams, in particular, has been largely investigated through experiments and simulations. Based on previous works of literature, the paper focuses on the strengthening effects of structural silicone joints on the global LTB response of glass beams. Analytical and numerical calculations are performed on various glass beams, in order to highlight the effects of continuous lateral restraints on their critical buckling moment. Shear tests are performed on small silicone sealant joints. Interesting correlations are found between joint properties and beams geometry.

Abstract
Glass beam-like elements are largely used in building structures in the form of primary load-bearing members. Large studies recently focused on specific structural behaviours under various loading and boundary conditions. Lateral-torsional buckling (LTB) of beams, in particular, has been largely investigated through experiments and simulations. Based on previous works of literature, the paper focuses on the strengthening effects of structural silicone joints on the global LTB response of glass beams. Analytical and numerical calculations are performed on various glass beams, in order to highlight the effects of continuous lateral restraints on their critical buckling moment. Shear tests are performed on small silicone sealant joints. Interesting correlations are found between joint properties and beams geometry.Pubblicazioni consigliate
