Design of pane-like laminated glass columns

摘要

To achieve transparency of buildings, load-bearing elements made of glass are essential, such as pane-like glass columns with laminated sections of heat-strengthened or toughened glass. An ultimate limit state design of such structures requires consideration of the composite interlayer. Using second order theory and the elastic shear bond between the glass layers allows the prediction of load-deflection of a laminated glass section under axial compression force. The introduction of a limit state function then results in equations for European buckling curves, which are also presented in this paper. The validity of these analytical equations is shown by experimental studies. Stability experiments on laminated glass columns were performed under variation of loading type and loading rate at room temperature. Laminated glass sections of heat-strengthened and toughened glass are the focus of this study.
