The European Commission has a strong interest on the development of the Eurocodes to achieve a further harmonisation of design rules in Europe and the revision process of all Eurocodes has started 2015. The second generation of the Eurocodes is expected to be published starting from 2025. The main objectives of the revision are the im-provement of the Ease-of-Use of the Eurocodes for practical users, the reduction of National Determined Parameters and the further harmonisation and inclusion of state-of-the-art. After an intensive discussion within CEN/TC 250 it was defined that the Eu-rocodes are addressed to competent civil, structural and geotechnical engineers, typi-cally qualified professionals able to work independently in relevant fields [1].
This paper provides an overview to the CEN Enquiry draft of the European design standard EN 1995-1-2 entitled Eurocode 5: Design of timber structures — Part 1-2: Structural fire design [2]. The revision work of the Eurocode 5, fire part (EN 1995-1-2 [3]) was performed by a Project Team (PT), which consisted of Andrea Frangi (chair, ETH), Alar Just (TalTech), Norman Werther (TU Munich), Jouni Hakkarainen (Eurofins), Joachim Schmid (ETH), and additional members from 2021 – Harald Krenn (KLH), Re-naud Blondeau (Stora Enso) and Gordian Stapf (Henkel).
Basis for the drafting work are extensive documents, reports and publications with the update state-of-the-art with regard to the structural fire behaviour and fire design of timber structures, e.g. the European Technical Guideline “Fire safety in timber build-ings” [4] or the reports prepared in the frame of the concluded COST Action FP1404 [5-7]. The PT started its work in June 2018 and reported regularly to the Working Group WG4 of CEN/TC250/SC5, which is responsible for the revision of EN 1995-1-2. During the last years, the PT prepared three drafts, which were reviewed by the WG4 and commented by the national standardisation bodies. The first draft (May 2019, 75 pages) received 265 comments, the second draft (Mai 2020, 134 pages) 624 comments and the third draft (November 2020, 138 pages) 364 comments. The final draft of EN 1995-1-2 was submitted at the end of August 2021 and received 396 comments. The CEN Enquiry of the document will start in September 2023, the publication will be at the end of 2025.
