On the shape and size of initial geometrical imperfections of structural glass members

On the shape and size of initial geometrical imperfections of structural glass members

Paper in proceedings (conference paper)

Buckling resistance is major design parameter for many structural glass components. Buckling resistance is influenced by several parameters: boundary conditions, slenderness and initial imperfections. Initial imperfections, in particular initial geometrical out-of plane curvatures are very poorly presented in literature. In this paper measuring and determining of initial geometrical imperfections of fifteen specimens are presented. These fifteen specimens will be experimentally tested on flexural buckling resistance in future. Measured specimens had the same dimensions but they had different composition – there are made from monolithic glass or laminated glass using PVB or EVA foil bonding together float glass panes or fully tempered glass panes. The shape of initial overall bow was measured using CARL ZEISS testing equipment. Information about initial curvature shapes and amplitudes are major conclusions resulting from statistical evaluation of experiments.
