Buckling analysis of simply supported flat glass panels subjected to in-plane uniaxial compressive and edgewise shear loads

Glass panels are widely used in modern architectures in the form of stiffeners and load-carrying elements. The frequent use of structural glass and the lack of standardized rules for designers gradually increased the interesting of scientists and researchers in the analysis of structural behaviors associated to various combinations of boundary and loading conditions. Buckling failure certainly represents one of the most crucial condition of collapse. In the paper, particular attention is dedicated to the buckling response of simply supported glass panels subjected to combined in-plane compressive and shearing forces. Based on large series of numerical incremental simulations, the effects of loading ratios, imperfection shapes, slenderness ratios and glass types on their buckling response are investigated. At last, based on analytical interaction formulations of literature, a normalized domain is proposed for their stability check
