Comparative Analysis of the Glass Plate Design

In this video, Ivana Rakić presents a comparative analysis of the economic impact of designing glass elements according to different standards, focusing on the new European draft standard FprEN 19100-1(2,3):2023, the existing EN 16612:2019, and the American ASTM E1300-16. The study examines common double-glazed insulating units under wind load, using the minimal required glass thickness for loadbearing resistance as the key comparison criterion. The results indicate that for annealed glass, all three standards yield similar economic outcomes. However, for heat-treated glass like heat-strengthened and thermally toughened glass, the new FprEN 19100 standard leads to a lower capacity utilisation factor, making it the most economical design choice, while the ASTM standard is the least economical. The analysis concludes that the choice of standard significantly influences design economy and highlights the need for further research incorporating factors like safety and long-term performance for a more comprehensive understanding. The video was produced by the Open GLASSroom project. Special thanks to Ivana Rakić and Nebojša Buljan for contributing to the Open GLASSroom OER collection.
