Experimental investigation of point-fixed laminated glass with enhanced post-breakage capacity

For many years, the transparency of glass has been a major feature that has excited architects to search for new applications for this material in architecture. Laminated glass is commonly used for structural elements. This requires a durable bond between at least two glass layers and an interlayer. When the glass is fractured, the interlayer holds the glass fragments together. Introducing reinforcement into the cross-section of glass laminates is a way to improve the load-bearing capacity in the post-failure phase. This paper summarises the main results of the research project "Innovative solutions for point-fixed laminated glass with increased load-bearing capacity" funded by the National Centre for Research and Development (NCBR) under the LIDER XI Programme. The article presents the results of destructive tests on laminated glass panes in three load configurations: in-plane, perpendicular to the plane, and combined loading. An important aspect of the work is the testing of full-scale elements. The results of the research can be applied directly to the safety analysis of glass structures, making them significant in terms of failure prevention.
