Some Highlights on the New Version of EN 1992-1-2 (Eurocode 2, Fire Part)
Revision process of Eurocode 2 relating to concrete structural design is ready for the final step, the Formal Vote in CEN TC 250 Structural Eurocodes at the beginning of 2023. This paper summarizes the main changes and new developments presented by this revision in prEN 1992-1-2 with regard to the version currently in force. It will focus mainly in the introduction on some changes in the structure of the document and the reduction of the number of Nationally Determined Parameters (NDPs). Additionally, some changes and novelties in the properties of concrete, reinforcing and prestressing steel with temperature are commented. Another important point is the novelties in the design and verification methods (tables, simplified and advanced), focusing in the simplified methods and an analytical formulation to find the temperature in rectangular and circular cross-sections. Finally, the new approach in the treatment of concrete spalling that simplifies and clarifies the measures to avoid it and new developments in the Annexes section are discussed.
