Buckling resistance and buckling curves of pane-like glass columns with monolithic sections of heat strengthened and tempered glass

Abstract

There is some knowledge on the stability behaviour of glass panes under axial loading, i.e. of their buckling stability. However, only a few investigations have been performed so far in this direction, predominantly at cross-sections with monopanes and sporadically at cross-sections with laminated glass. Thus a research project was initiated by the German Steel Construction Association (DSTV) and the German Ministry of Economics, by which the buckling of pane-like glass columns with mono- and laminated sections was thoroughly investigated. The article focuses on the results for buckling with monolithic sections of heat strengthened and tempered glass, giving buckling curves proposed by derivations and experiments.
