Tkach R. Load bearing capacity and deformability of stacked glass columns

The dissertation is devoted to the theoretical and experimental study of the stacked glass columns tested in the central compression under the static loading and determining of their bearing capacity and deformability in laboratory conditions. The test specimens 8 had different cross-sections, different heights and were made of ordinary, heatstrengthened and tempered glass using triplexing technology. Stacked glass columns were tested in central compression with different fixing on supports, namely hinged and elasticpliable fixing of supports, in accordance with the developed method of experimental study. A modern optical method is applied to measure the deformations of columns, namely the method of two-dimensional digital image correlation. Furthermore, the real values of physical and mechanical properties of the glass from which the columns were made were determined. Based on the results of theoretical and experimental study, we developed a method of calculating the bearing capacity of the stacked glass columns tested in central compression and recommendations for their design, which were implemented at construction sites.
