CEN/TC 250 is responsible for all Structural Eurocodes. This European Standard shall be given

34、 the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at the latest by March 2010. This document supersedes ENV 1992-2:1997. According to the CEN/CENELEC Internal Regulation

35、s, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, N

36、etherlands, Norway, Poland, Portugal, R mania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. Background to the Eurocode programme See EN 1992-1-1.

37、en Eurocodes and harmonised 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 s

38、pecific 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 EN 1992-1-1 are applicable to the de

39、sign of bridges unless specifically deleted or varied by EN 1992-2. It has been appropriate to introduce in EN 1992-2 some material, in the form of new clauses or amplifications of clauses in EN 1992-1-1, which is not bridge specific and which strictly belongs to EN 1992-1-1. These new clauses and a

40、mplifications are deemed valid interpretations of EN 1992-1-1 and designs complying with the requirements of EN 1992-2 are deemed to comply with the Principles of EN 1992-1-1. EN 1992-2:2005 + AC:2008 (E) DIN EN 1992-2:2010-12 o6 clauses in EN 1992-2 that modify those in EN 1992-1-1 are numbered by

41、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. For the design of new structures, EN 1992-2 is intended to be used, for direct

42、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, t

43、esting 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

44、 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. National Annex for EN 1992-2 This standard gives values with

45、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 bridges to be constructed in the relevant country. National choice is allowed

46、in EN 1992-2 through the following clauses: 3.1.2 (102)P 3.1.6 (101)P 3.1.6 (102)P 3.2.4 (101)P 4.2 (105) 4.2 (106) 4.4.1.2 (109) 5.1.3 (101)P 5.2 (105) 5.3.2.2 (104) 5.5 (104) 5.7 (105) 6.1 (109) 6.1 (110) 6.2.2 (101) 6.2.3 (103) 6.2.3 (107) 6.2.3 (109) 6.8.1 (102) 6.8.7 (101) 7.2 (102) 7.3.1 (105)
