Since the beginning of 2021, CEN/TS 19100 Design of Glass Structures has been available in its first three parts. The fourth part is expected soon. This Technical Specification of the European standards organisation CEN is as a pre-standard of a corresponding future Eurocode. These documents constitute the first ever comprehensive design code for the entire structural glass engineering field on the European market for the first time. In addition to a clear outline, the Technical Specification has been drafted to be compatible with EN 1990 “Basis of Design” and to address glass-specific design matters, particularly related to robustness and redundancy. Although the standard still has the status of a CEN/TS, thereby allowing the European nations the option of whether to introduce it, either in full or in parts, it already contains national openings through which the European countries can adapt the design results to their own safety level by National Determined Parameters (NDPs). Such an approach already anticipates the future Eurocode, which is expected to be published as EN 19100—Design of Glass Structures. This article provides some context on the history and concept behind the new documents and gives an overview of the design rules and the corresponding technical background of the different parts of CEN/TS 19100.

This paper presents the results of research conducted within R&D project. The primary goal was to apply the current state of the art technology in aluminium to a timber-based frames, but also to improve the energy performance of the building envelope and create environmentally friendly product, which physical, structural and aesthetic performances are equal to or even better than equivalent aluminium systems.

Na primjeru projekta izvedene staklene stijene ovješene na prednapetim vertikalnim kablovima, u radu su kratko opisane njihove konstrukcijske značajke, a detaljnije razrađena načela proračuna. Uspoređeni su rezultati primjene dvaju pristupa u modeliranju: integralnog, koji uključuje i glavnu nosivu konstrukcije te interakciju u zonama oslonaca ostakljenja, te pojednostavnjenog, sa sekvencijalno modeliranim kablovima i simulacijom interakcije s glavnom konstrukcijom oprugama zamjenskih krutosti u točkama sidrenja kablova. Analizirane su prednosti, razlozi i posljedice primjene modela na ponašanje staklene stijene i cjelovite konstrukcije.

In unitised curtain walls, the transfer of horizontal loads, mainly wind loads, from the upper into the lower unit is achieved through the head/notch interlocking connection. Optimisation of the machining process would require a sharp root of the notch, causing an increase in the stress concentration. In order to predict fatigue resistance during design life, the influence of the radius at the root of the notch has been tested in both static and cyclic regimes. The cyclic regime is based on the load history equivalent of 50 years of wind exposure. Numerical simulations on the test assembly have been conducted in order to verify their adequacy for future research on similar issues. The experimental results demonstrated that, for the given specimen shape and alloy, a sharp notch would not lead to premature failure, and such a detail is safe from the purview of damage-tolerant design.
