Standardized buckling curves for the verification of glass columns, beams and panels

Monolithic and laminated glass elements are frequently subjected to buckling phenomena. Nevertheless, several aspects make complex the description of their structural response through analytical models of general applicability. In addition, classical models proposed by standards for the verification of steel, timber or composite structures cannot be directly applied to glass, since they do not taken into account some aspects typical of glass elements. The paper proposes a general approach for the buckling verification of monolithic and 2 or 3-layer laminated glass columns, beams and panels under in-plane compression or shear. Calibrated to experimental and numerical data collected from literature, standardized buckling curves are proposed to be applied in daily practice.
