This standard gives values with notes indicating where national choices may have to be made. Therefore the National Standard implementing EN 1992-2 should have a National annex containing all Nationally Determined Parameters to be used for the design of buildings and civil engineering works to be constructed in the relevant country.

National choice is allowed in EN1992-2 through the following clauses:

Foreword

This European Standard EN 1992, Eurocode 2: Design of concrete structures: Concrete bridges - Design and Detailing Rules, has been prepared on behalf of Technical Committee CEN/TC250 « Structural Eurocodes », the Secretariat of which is held by BSI. CEN/TC250 is responsible for all Structural Eurocodes.

This Eurocode supersedes ENV 1992-2.

Background to the Eurocode programme: see EN 1992-1-1.

Status and field of application of Eurocodes: see EN 1992-1-1.

National Standards implementing Eurocodes: see EN 1992-1-1.

Links between Eurocodes and harmonized technical specifications (ENs and ETAs) for products: see EN 1992-1-1.

Additional information specific to EN 1992-2 and link to EN 1992-1-1

EN 1992-2 describes the principles and requirements for safety, serviceability and durability of concrete structures, together with specific provisions for bridges. It is based on the limit state concept used in conjunction with a partial factor method.

• EN 1992 -2 gives Principles and Application Rules for the design of bridges in addition to those stated in EN 1992 - 1- 1, all relevant clauses of which are applicable to the design of bridges unless specifically deleted or varied by EN 1992 - 2. It has been necessary to introduce in 1992 -2 some material, which is not bridge specific and which strictly belongs to Part 1-1 in the form of new clauses or amplifications of some clauses of Part 1-1. These are deemed valid interpretations of Part 1 -1 and designs complying with the requirements of EN 1992 -2 are deemed to comply with the Principles of EN 1992 -1 -1.
• clauses in EN 1992–2 that modify those in EN 1992–1–1 are numbered by adding '100' to the corresponding clause number in EN 1992–1–1.
• when additional clauses or sub-clauses are introduced in EN 1992–2, these are numbered by adding '101' to the last relevant clause or sub-clause in EN 1992–1–1.

EN 1992-2 is based on the limit state concept used in conjunction with a partial factor method.

For the design of new structures, EN 1992-2 is intended to be used, for direct application, together with other parts of EN 1992, Eurocodes EN 1990,1991, 1997 and 1998.

EN 1992-2 also serves as a reference document for other CEN TCs concerning structural matters.

EN 1992-2 is intended for use by:

• committees drafting other standards for structural design and related product, testing and execution standards;
• clients (e.g. for the formulation of their specific requirements on reliability levels and durability);
• designers and constructors ;
• relevant authorities.

Numerical values for partial factors and other reliability parameters are recommended as basic values that provide an acceptable level of reliability. They have been selected assuming that an

appropriate level of workmanship and of quality management applies. When EN 1992-2 is used as a base document by other CEN/TCs the same values need to be taken.

This standard gives values with notes indicating where national choices may have to be made. Therefore the National Standard implementing EN 1992-2 should have a National annex containing all Nationally Determined Parameters to be used for the design of buildings and civil engineering works to be constructed in the relevant country.

National choice is allowed in EN1992-2 through the following clauses:

3.1.2 (2) 3.1.6 (1) 3.1.6 (2) 3.2.4 (1) 4.2.3 (3) 4.4.1.2 (2) 4.4.1.2 (3) 5.1.3 (1)P 5.3.2.2 (2) 5.5 (2) 5.7 (2)
