It supersedes DD ENV 1992-2:2001 which is withdrawn.The start and finish of text introdu
3、ced or altered by corrigendum is indicated in the text by tags. Text altered by CEN corrigendum July 2008 is indicated in the text by .The structural Eurocodes are divided into packages by grouping Eurocodes for each of the main materials, concrete, steel, composite concrete and steel, timber, mason
4、ry and aluminium. This is to enable a common date of withdrawal (DOW) for all the relevant parts that are needed for a particular design. The conflicting national standards will be withdrawn at the end of the coexistence period, after all the EN Eurocodes of a package are available.Following publica
5、tion of the EN, there is a period allowed for national calibration during which the National Annex is issued, followed by acoexistence period of a maximum three years. During the coexistence period Member States will be encouraged to adapt their national provisions.At the end of this coexistence per

CEN/TC 250 is
35、responsible for all StructuralEurocodes.This European Standard shall be given the status of a national standard, either by publication of an identicaltext or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at thelatest by March 2010.According to the
36、 CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,Luxembourg

39、estructures, together with specific provisions for bridges. It is based on the limit state concept used inconjunction with a partial factor method. EN 1992-2 gives Principles and Application Rules for the design of bridges in addition to those stated inEN 1992-1-1. All relevant clauses of EN 1992-1-
40、1 are applicable to the design of bridges unlessspecifically deleted or varied by EN 1992-2. It has been appropriate to introduce in EN 1992-2 somematerial, in the form of new clauses or amplifications of clauses in EN 1992-1-1, which is not bridgespecific and which strictly belongs to EN 1992-1-1.
41、These new clauses and amplifications are deemedvalid interpretations of EN 1992-1-1 and designs complying with the requirements of EN 1992-2 aredeemed to comply with the Principles of EN 1992-1-1.BS EN 1992-2:2005EN 1992-2:2005 (E)6 clauses in EN 1992-2 that modify those in EN 1992-1-1 are numbered
42、by adding 100 to thecorresponding clause number in EN 1992-1-1. when additional clauses or sub-clauses are introduced in EN 1992-2, these are numbered by adding 101to the last relevant clause or sub-clause in EN 1992-1-1.For the design of new structures, EN 1992-2 is intended to be used, for direct
43、application, together with otherparts 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, test
44、ing and executionstandards; 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 thatprovide an ac
45、ceptable level of reliability. They have been selected assuming that an appropriate level ofworkmanship and of quality management applies. When EN 1992-2 is used as a base document by otherCEN/TCs the same values need to be taken.National Annex for EN 1992-2This standard gives values with notes indi
46、cating where national choices may have to be made. Therefore theNational Standard implementing EN 1992-2 should have a National Annex containing all NationallyDetermined Parameters to be used for the design of bridges to be constructed in the relevant country.National choice is allowed in EN 1992-2
