1、BRITISH STANDARD BS EN 13693:2004 +A1:2009 Precast concrete products Special roof elements ICS 91.100.30 National foreword This British Standard is the UK implementation of EN 13693:2004+A1:2009. It supersedes BS EN 13693:2004 which is withdrawn. The start and finish of text introduced or altered by
2、 amendment is indicated in the text by tags. Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment A1 is indicated by !“. The UK participation in its preparation was entrusted to Technical Committee B/524, Precast concrete products. A l
3、ist of organizations represented on this committee can be obtained on request to its secretary. EN 13693 is a 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 Con- struction
4、Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 13693 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 Commun
5、ities. EN 13693 is the subject of transitional arrangements agreed under the Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 13993 and their corresponding national standard(s). It is intended that this period will comprise a nominal nine month
6、 period, during which any required changes to national regulations are to be made, followed by a further nominal 12 month period 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 At the end of this co-existence period, the national standard(s) will be withdrawn.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 st
7、andards. This publication 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. BS EN 13693:2004+A1:2009 This British Standard was published under th

21、as examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229 CEN/TC 250, particularly 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 endorsem

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 Construction Products Directive (89/106/EEC) of European Union (EU). For relationship with EU Directive
24、(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 made to EN 13369: Common rules for precast products, from which also the relevant requirements of the EN 206
25、-1: Concrete - Part 1: Specification, performances, production and conformity are taken. The references to EN 13369 by CEN/TC229 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
26、 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 an European prestandard. In all countries it can be accompanied by alternatives for national application and it shall
27、not be treated as a European Standard. The programme 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
28、12843, Precast concrete products - Masts and poles EN 13224, Precast concrete products - Ribbed floor elements EN 13225, Precast concrete products - Linear structural elements EN 13693, Precast concrete products - Special roof elements !EN 13747, Precast concrete products - Floor plates for floor sy

Where, in default of applicab
31、ility 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
32、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, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Polan

BS EN 13693:2004+A1:2009 EN 13693:2004+A1:2009 (E)5 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 p
34、roduction operations carried out in the factory. For design rules and resistance to fire principal reference is made to EN 1992-1-1 and EN 1992-1-2. Additional complementary rules are provided where necessary. In Clause 4.3.3 and 4.3.4 this document includes specific provisions resulting from the ap
35、plication of EN 1992-1-1 and EN 1992-1-2 rules to the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1 and EN 1992-1-2. BS EN 13693:2004+A1:2009 EN 13693:2004+A1:2009 (E)6 1 Scope This document identifies the requirements, the basic performanc
36、e criteria and the evaluation of conformity for special precast roof elements made of reinforced or prestressed normal weight concrete, used for the construction of buildings, with or without separating function with respect to fire resistance. NOTE The title of special roof elements refers to thin-
37、walled structural elements with deformable transverse profile, such as folded plates, or shell elements, the intended use being specific for roofings with their typical loads. This type of elements combines the overall flexural behaviour along the main span with a complex distribution of in-plane fo
38、rces and local moments. Other types of elements can be used in roofing, such as ribbed units, floor slabs, . . For these elements reference shall be made to their respective product standards. !This document identifies also the requirements, the basic performance criteria and the evaluation of confo
39、rmity of complementary elements made of reinforced or prestressed normal weight concrete, possibly used in combination with the main roof elements, such as load bearing shuttering plates and shells, for which reference shall be made to Annex F.“ This document covers terminology, performance criteria
40、, tolerances, relevant physical properties, test methods, and aspects of transport and erection. This document does not deal with seismic behaviour. This document does not cover load bearing capacity determined by testing. 2 Normative references The following referenced documents are indispensable f

44、nt materials of concrete, reinforcing and prestressing steel, inserts and connections, the relevant clauses of EN 13369:2004 4.1 shall apply. In particular the ultimate tensile and tensile yield strength of steel shall be considered. BS EN 13693:2004+A1:2009 EN 13693:2004+A1:2009 (E)7 4.2 Production
45、 requirements 4.2.1 Concrete production Clause 4.2.1 of EN 13369:2004 shall apply. In particular the compressive strength of concrete shall be considered. 4.2.2 Hardened concrete Clause 4.2.2 of EN 13369:2004 shall apply. 4.2.3 Structural reinforcement In addition to Clause 4.2.3 of EN 13369:2004, t
46、he following specific rules shall apply. Special care shall be given to ensure a stable positioning of reinforcement in the thin slabs (t 100 mm). For welded meshes and isolated bars in thin slabs, concrete covers against formworks shall be ensured by a sufficiently dense distribution of spacers. Ac
47、cess of workers, as well as concrete casting and compacting, shall be made in such a way so to avoid displacements and deformations of steel reinforcement with respect to the intended positioning and shapes. 4.3 Finished product requirements 4.3.1 Geometrical properties 4.3.1.1 Production tolerances
48、 The following values of production tolerances shall be used. The values are expressed in mm and refer to the measure described in Figure 1. Tolerances refer to the deviations with respect to the design (nominal) values indicated in project documentation (inclusive of possible cambers). Measurement
