The Application of Waste Float Glass, Recycled in Structural Beams made with the Glass Casting Method

Yu, R. (author), Bristogianni, T. (author), Veer, F.A. (author), Nijsse, R. (author)

It is not obvious to talk about glass recycling when we realize that a mature recycling procedure for glass bottles is already working well. However, apart from glass bottles, unfortunately, that a large amount of glass will disappear into landfills. This large quantity of unrecycled glass indicates that there is a large potential in upgrading...

Eskes, A.M. (author), de Krom, Diana (author), Bristogianni, T. (author), Rammig, L.M. (author), Veer, F.A. (author), Nijsse, R. (author)

Connecting glass with heat bonds is a way to create all-transparent glass structures. Two methods have been researched in theory and practice, glass welding, through local heating, and glass fusion through global heating. Both methods have been applied to produce 10 mm thick T-sections of soda lime glass while preventing thermal shock failure...

Education on Structural Glass Design: Redefining glass through the design of innovative, full-glass structures

Oikonomopoulou, F. (author), Bristogianni, T. (author), Louter, P.C. (author), Veer, F.A. (author), Nijsse, R. (author)

In many famous architectural works, it is the structure and materiality of the building that manifest the project’s innovation. In such works, the structural system of the building becomes the primary form of expression. Ergo, the ability to understand the principles of structural engineering and design, and the motivation to experiment with new...

Prediction of Strength for Inhomogeneous: Defective Glass Elements Based on the Sequential Partitioning of the Data and Weibull Statistical Distribution

Shabetia, Alexander (author), Rodichev, Yurii (author), Veer, F.A. (author), Soroka, Elena (author)

An analytical approach based on the on the sequential partitioning of the data and Weibull Statistical Distribution for inhomogeneous - defective materials is proposed. It allows assessing the guaranteed strength of glass structures for the low probability of fracture with a higher degree of reliability. Parameters of equations for the piecewise...

Structural Strength of Laminated Glass

Rodichev, Yurii (author), Veer, F.A. (author), Strizhalo, Vladimir (author), Soroka, Elena (author), Shabetia, Alexander (author)

The subject area "structural strength of materials" is defined generally as а complex of strength characteristics of materials and structural elements, obtained under special mechanical tests. It is shown that these tests should take into account not only the physical and mechanical properties of the material, but technology, blank processing,...

Cast Glass Components out of Recycled Glass: Potential and Limitations of Upgrading Waste to Load-bearing Structures

Bristogianni, T. (author), Oikonomopoulou, F. (author), Justino de Lima, C.L. (author), Veer, F.A. (author), Nijsse, R. (author)

Although in theory glass can be endlessly remelted without loss in quality, in practice only a small percentage gets recycled, mainly by the packaging industry. Most of the discarded glass fails to pass the high quality standards of the prevailing glass industry -due to coatings, adhesives, other contaminants or incompatibility of the recipe-...

Design and Experimental Testing of All Glass Sandwich Panels: An Experimental and Numerical Study for the Glass Floors of the Acropolis Museum

Vitalis, Dimitrios (author), Veer, F.A. (author), Oikonomopoulou, F. (author)

This paper describes the engineering steps taken in order to investigate the potential of glass sandwich elements, made of 2 glass skins separated by a glass core in the form of spacers, as a way to create planar elements with a high stiffness to weight ratio, reducing material consumption in structural glazing applications. The aim is to...

A Re-evaluation of the Physiochemistry of Glass on the Basis of Recent Developments and its Relevance to the Glass Industry

Veer, F.A. (author), Bristogianni, Telesilla (author), Justino de Lima, Clarissa (author)

The classical image of glass is that of a rigid, transparent brittle material characterized by a non-crystalline microstructure. This 19th and 20th century image however is mostly based on the contrast between soda lime glass and metals. It does not really make sense in the 21th century where more modern testing methods have increased our...

A Novel, Demountable Structural Glass System Out of Dry-Assembly, Interlocking Cast Glass Components

Oikonomopoulou, F. (author), Bristogianni, T. (author), Barou, L. (author), Jacobs, Erwin (author), Frigo, G. (author), Veer, F.A. (author), Nijsse, R. (author)

Cast glass components are a promising solution for engineering pure glass structures of high transparency and load-carrying capacity due to their large cross-sectional area and monolithic nature. Currently, the few realized structures employing cast glass components rely either on a steel substructure or on an adhesive of high bonding strength...

Innovative Glass Recipes Containing Industrial Waste Materials

Justino de Lima, C.L. (author), Veer, F.A. (author), Copuroglu, Oguzhan (author), Nijsse, R. (author)

The growth of the industrial production generates a high volume of waste materials. These products have a significant impact on the environment. Therefore, the valorization of industrial wastes, especially those produced in huge quantities, is an important social and ecological issue. Waste reuse and recycling could help to develop new...

Dematerialization of the Ruins: Glass as a Promising Restorative Material for the Consolidation of Historic Structures

Barou, L. (author), Oikonomopoulou, F. (author), Bristogianni, T. (author), Veer, F.A. (author), Nijsse, R. (author)

This research investigates the potential of glass as a new design tool to highlight and safeguard our historic structures. Current restoration and conservation treatments with traditional materials bear the risk of conjecture between the original and new elements, whereas the high consolidation demands often result in visually invasive and...
