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 stan- dards organisation CEN is as a pre-standard of a cor- responding future Eurocode. These documents consti- tute the first ever comprehensive design code for the entire structural glass engineering field on the Euro- pean 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, particu- larly 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 Euro- pean countries can adapt the design results to their own safety level by National Determined Parame- ters (NDPs). Such an approach already anticipates the future Eurocode, which is expected to be published as EN 19100—Design of Glass Structures. This arti- cle provides some context on the history and concept behind the new documents and gives an overview of the design rules and the corresponding technical back- ground of the different parts of CEN/TS 19100.
