“…Alternative configurations of profile columns, i.e. H, T, X and square profiles, and their compressive behaviour have been explored experimentally, numerically and analytically by Ouwerkerk (2011), Aiello et al (2011), Campione and Rondello (2014, Overend et al (2005) and Kalamar et al (2016). The findings demonstrate that the 3-dimensional geometry of such glass columns results in an increased structural resis-tance and stiffness.…”

“…The adhesive connection between adjacent glass components plays a key role in the overall structural performance of glass columns (Kalamar et al 2016). Thus, the degree of mechanical collaboration between the rods is highly dependent on the applied adhesive.…”

“…Nevertheless, despite the continuously ascending use of glass in structural components such as beams, portals, shear walls and selfcarrying façades over the last decades, free-standing glass columns are still in a very early stage of development. This can be attributed to the insufficient knowledge regarding their structural behaviour and load carrying capacity under exceptional loading conditions (Kalamar et al 2016). …”

Glass columns are a promising solution for transparent structural members, capable of transferring the compressive loads in a building while allowing for light and space continuity. Several different types of allglass columns have been explored in the past, nevertheless, they are seldom applied in construction. Reasons include complications in fabrication, lack of adequate strength data but foremost the decreased safety due to the inherent brittleness of glass. This work presents the engineering steps towards the realization of the bundled glass column, from its fabrication method to the experimental testing of series of prototypes in several lengths. Composed of multiple adhesively bonded standardized extruded borosilicate rods, this column can be manufactured relatively easily, achieving a high visual result and sufficient load-bearing capacity. Initially, compressive testing is conducted on series of small-scale prototypes to evaluate the degree of coupling of the rods and the influence of spliced joints along the length of the individual components. Based on the findings, prototypes on a scale relevant to buildings are produced and The results demonstrate that the designed bundled column can perform monolithically under loading and has sufficient load-carrying capacity to be considered a structural element. Post-tensioning of the column can contribute to a consistent failure but further development is necessary so that sufficient cooperation between the glass and the steel tendon is achieved.

“…Chiara Bedon and Claudio Amadio investigated a long time ago the possibility of design of glass structures with application of VEM models and laboratory experiments [4,5]. Roman Kalamar [6] investigated the load bearing capacity of glass hollow box columns. These researches demonstrate that the designing of glass columns -rather the designing of glass materials -became one of the most investigated topics.…”

the initial imperfection of the structural elements must be taken into account in case of the modern building designing. these imperfections are local or overall defects of the glass elements. these defects are able to reduce significantly the load bearing capacity and the stability limits as well. the initial curvature and the imperfections of the elements are taken into account at the stability designing in case of the general building materials. the applied limits depended on the cross-section of the structural elements. Glass designing for load bearing elements has been applied since a few decades, however there are limits for initial imperfections. more than 240 small scaled i-shaped glass columns were loaded until fracture under laboratory conditions. the lateral buckling was investigated based on the individual experimental procedure. one of the most important properties of the glass columns are the initial imperfections. the higher overall bow and roller wave values can cause disadvantages at the load bearing capacity of the glass columns; however, the roller waves also can increase the critical buckling force according to euler. these specific factors of the glass specimens were measured by a new measurement method to analyse the effects of the imperfections on the load bearing capacity in case of a small amount of the specimens. the new method contains a reference Point system and it is able to detect these imperfections in high accuracy. the new measurement method is also able to provide information about the glass manufacturing effects on the plate glass shape. keywords: glass, flexural buckling factors, own shape, tin-air side, reference point system andrás Jakab PhD student at the Bme, msc civil engineer. Fields of interests: glass construction, glass columns, non-destructive testing methods, point-fixed glasses construction technology and management.
