This is a Norwegian Prestandard
The Norwegian Prestandard SN-EN 1998-2:2025 represents a second-generation Eurocode. Prestandards (SN-EN) for second-generation Eurocodes are published to provide the industry with an opportunity to familiarize itself with the content. These prestandards do not replace the first-generation Eurocodes.

In Norway, all second-generation Eurocodes will be published collectively as Norwegian Standards (NS-EN) along with corresponding national annexes. All first-generation Eurocodes with national annexes will remain valid Norwegian standards until then and will be withdrawn simultaneously with the publication of the second-generation Eurocodes.
Abstract
EN 1998-2 is intended to be applied to the design of new bridges in seismic regions. It covers the design of reinforced concrete, steel and composite steel-concrete bridges and provides guidance for the design of timber bridges. EN 1998-2 is applicable to the seismic design of bridges exploiting ductility in structural members or through the use of antiseismic devices. When ductility is exploited, this part primarily covers bridges in which the horizontal seismic actions are mainly resisted through bending of the piers or at the abutments; i.e. of bridges composed of vertical or nearly vertical pier systems supporting the traffic deck superstructure. It is also applicable to the seismic design of arched bridges, although its provisions should not be considered as fully covering these cases.Suspension bridges and masonry bridges, moveable bridges and floating bridges are not included in the scope of EN 1998-2.
