17、d This document (EN 15258:2008) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR, and was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229-CEN/TC 250, particularly for its compatibili

18、ty with structural Eurocodes. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by July 2010. Attention is drawn to th

19、e possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free

20、Trade Association, and supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. This standard is one of a series of product standards for precast concrete products. For common aspects reference is

21、 made to EN 13369:2004: Common rules for precast products, from which also the relevant requirements of the EN 206-1: Concrete Part 1: Specification, performances, production and conformity are taken. The references to EN 13369:2004 by CEN/TC 229 product standards are intended to make them homogeneo

22、us and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by ENV 13670-1, Execution of concrete structures Part 1: Common rules, which has at the moment the status of

23、an European prestandard. In all countries it can be accompanied by alternatives for national application and it shall not be treated as a European standard. The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting on several part

29、odes (EN 1992-1-1:2004 and EN 1992-1-2:2004). Where, in default of applicability conditions of EN Eurocodes to the works of destination, design Provisions other than EN Eurocodes are used for mechanical strength, the conditions to affix CE marking to the product are described in ZA.3.4 and Z.A 3.5.

30、According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,

31、Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 15258:2008EN 15258:2008 (E) 6 Introduction The evaluation of conformity given in this standard refers to the precast elements which are s

32、upplied to the market and covers all the production operations carried out in the factory. For design rules reference is made to EN 1992-1-1:2004. Additional complementary rules are provided where necessary. BS EN 15258:2008EN 15258:2008 (E) 7 1 Scope This European Standard deals with the requiremen

33、ts, the basic performance criteria and evaluation of conformity for precast elements made of plain, reinforced or prestressed normal weight concrete, used for the construction of retaining walls. The products covered by this European Standard are intended to be used as part of retaining walls in app

34、lications such as: to retain natural ground excavations and trenches; to retain earth fills for roads, platforms, etc.; in bridge abutments and their flank walls; to retain several kinds of loose materials such as sand, gravel, etc. Some examples of precast elements considered in this European Stand

35、ard are shown in the Informative Annex B. The products may be used in seismic areas on condition that they fulfil the requirements specific to this use. This European Standard does not cover: products for retaining walls of tanks or reservoirs of liquids; retaining wall elements up to a height of 1,

36、0 m and those assembled to form retaining walls of up to 1,0 m in height (e.g. stacked flower boxes for dwarf walls) if the corresponding retaining wall is used for secondary loads (max. horizontal earth fill and with light surcharge); products for stacked planting boxes, having only faade functions

37、, and therefore not submitted to any loads (such as earth pressure loads, highway load effects, etc.); precast diaphragm walls (concrete sheet piling). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edi

38、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

46、) on full scale specimens of precast elements for retaining cantilever walls. This test may serve to confirm design assumptions and/or substitute calculations if there are no adequate models for some details (e.g. gusset). 5.2(1), 5.2(2)P and 5.2(3) of EN 1990:2002 shall apply. 4.3.3.6 Transient sit

47、uations The transient situations covered by this sub-clause relate to storage, handling, transport and installation. The strength and properties of the concrete retaining wall element to be considered in transient situations are those specified by the manufacturer at the time of delivery. Main and s

48、econdary transverse reinforcements provided in the wall element, as well as those used for lifting, shall be capable to withstand the loadings expected for the transient situations. In these transient situations temporary props or safe mounting racks, suitable for the product shall be used, if neces

49、sary, to maintain the precast elements in correct position and shape and to reduce the effects of the loadings. 4.3.3.7 Conditions for installation Wall elements shall be installed in accordance with technical specifications provided by the manufacturer. Wall elements shall be erected using temporary props or any device required by technical specifications to achieve their own resistance and their own stability in transitional stage, and safe working condition
