1、BRITISH STANDARD BS EN 15037-1:2008 Precast concrete products Beam-and-block floor systems Part 1: Beams ICS 91.100.30 BS EN 15037-1:2008 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 June 2008 BSI 2008 ISBN 978 0 580 54648 8 National fo
2、reword This British Standard is the UK implementation of EN 15037-1:2008. The UK participation in its preparation was entrusted to Technical Committee B/524, Precast concrete products. A list of organizations represented on this committee can be obtained on request to its secretary. EN 15037-1 is a
3、candidate “harmonized” European standard and fully takes into account the requirements of the European Commission mandate M/100, Precast concrete products, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 15037-1
4、as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. EN 15037-1:2008 is the subject of transitional arrangements agreed under the European Commission mandate.
5、 Member States have agreed a transition period for the co-existence of BS EN 15037-1:2008 and its corresponding national standard(s). It is intended that this period will comprise a period, usually nine months, after the date of availability of the European Standard, during which any required change
6、s to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. In the UK, there are no corresponding national standards of national origin. This pu
7、blication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. Amendments/corrigenda issued since publication DateComments W - - - - - - - 77- 7 -8-

20、xamined by and agreed with a joint working party appointed by the Liasion Group CEN/TC 229-TC 250, particulary for its compatibility 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 th
21、e latest by October 2008, and conflicting national standards shall be withdrawn at the latest by April 2011. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For re
22、lationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.

24、ck floor systems Part 5: Lightweight blocks 1) This standard is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369: Common rules for precast concrete products, from which also the relevant requirements of the EN 206-1: Concrete Part 1
25、: Specification, performance, production and conformity are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some
26、 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 a European Prestandard. In all countries it can be accompanied by alternatives for national application and it should not be treated as a E
27、uropean Standard. The program of standards for structural precast concrete products comprises the following standards, in some cases consisting of several parts: EN 1168, Precast concrete products Hollow core slabs EN 12794, Precast concrete products Foundation piles EN 12843, Precast concrete produ

Where, in default of applicability
31、conditions of EN Eurocodes to the works of destination, design Provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3.4. According to the CEN/CENELEC Internal Regulations, the national standa

BS EN 15037-1:2008 EN 15037-1:2008 (E) 6 Introduction The evaluation of conformity given in this standard refers to the completed precast elements which are supplied to the market and covers all the production operati
34、ons carried out in the factory. For design rules reference is made to EN 1992-1-1:2004. Additional complementary rules are provided where necessary. Recommendations for beam-and-block floor systems are presented in informative annexes about monolithism of composite floor systems (Annex C), detailing
35、 of supports and anchorage reinforcement (Annex D), design of composite floor systems (Annex E), design of self-bearing beams (Annex F), diaphragm action (Annex G), resistance to fire (Annex K) and acoustic insulation (Annex L). According to 1.2 of EN 1992-1-1:2004 the complementary rules, given in
36、informative annexes in this standard, comply with the relevant principles given in EN 1992-1-1. Because of the fact that the experimental evidence is mainly based on elements with limited depth and width this standard is applicable to elements with these limited dimensions. This limitation is not in
37、tended to prohibit the application of elements with larger sizes, but the experience is not yet wide enough to draw up standardised design rules. In 4.2.3, 4.3.2, 4.3.3 and 4.3.4, this standard includes specific provisions resulting from the application of EN 1992-1-1:2004 and EN 1992-1-2:2004 rules
38、 made specific for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1:2004 and EN 1992-1-2:2004. BS EN 15037-1:2008 EN 15037-1:2008 (E) 7 1 Scope This European Standard deals with the requirements, the basic performance criteria and evaluati
39、on of conformity for precast beams made of reinforced or prestressed normal weight concrete according to EN 1992-1-1:2004, with or without clay shell, used in conjunction with blocks in compliance with prEN 15037-2 or prEN 15037-3 or prEN 15037-4 or prEN 15037-5, with or without cast in-situ concret
40、e for the construction of beam-and-block floor and roof systems. Examples of typology of floor and roof systems are given in Annex B. It is essential that the total depth of the beam be comprised between 60 mm and 500 mm and the beams be at centres of not more than 1,00 m. For higher depth, it is es
41、sential that the precast concrete beams be in compliance with EN 13225. The products covered by this standard are intended to be used as structural floor and roof systems, including parking areas for light vehicles corresponding to traffic category F of EN 1991-1-1:2002, which are not subjected to f
42、atigue loading. The products may be used in seismic areas provided they fulfil the requirements specific to this use. 2 Normative references The following referenced documents are indispensable for the application of this document.
