NEW PROVISIONS FOR SEISMIC DESIGN OF BRIDGES

The paper presents an overview of the new provisions of the second generation of the EN 1998 standards dedicated to design of bridges for earthquake resistance based on available phase of development of standards. Main document Eurocode 8 – Design of structures for earthquake resistance – Part 2: Bridges (FprEN 1998-2:2024) is analysed in relation to the introductory Part 1-1: General rules and seismic action (FprEN 1998-1-1:2024) and basic document on Basis of structural and geotechnical design (FprEN 1990:2022) together with Part 1 on New structures (prEN 1990-1:2024). Authors aim to reveal the changes in the determination of seismic actions and in the approach to design of bridges for earthquake resistance and to emphasise the most important novelties.
