Foreword This document (EN 12737:2004+A1:2007) 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-TC250, 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of an identical text or by endorsement, at the latest by April 2008, and conflicting national standards shall be withdrawn at the latest by July 2009. This document supersedes EN 12737:2004. This document includes Amendment 1, approved by CEN on 2007-08-30. The start and finish of text introduced or altered by amendment is indicated in the text by tags !". !deleted text" !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 the Construction Products Directive (89/106/EEC). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document." This document is consistent with the Council Directive 2001/88/EC of 23 October 2001 amending Directive 91/630/EEC laying down minimum standards for the protection of pigs. 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, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

Floor slats for use solely by stock and stockmen shall be designed in accordance with the indicated vertical and horizontal variable characteristic loads. Self weight of floor slats and other additional loads (e.g. self weight of pen partitions, feeding troughs, .) shall be dealt with in the design. The following variable characteristic loads shall be taken:  a vertical characteristic linear load qk;  a vertical characteristic point load Fk,v;  a horizontal characteristic point load Fk,h. Values of qk, Fk,v and Fk,h shall be as given in Table 4. For single beams these values shall be multiplied by 1,1. !!!!Table 4"""" — Characteristic loading values Load class Linear load qk

Partial safety factors for material properties shall be 1,5 for concrete and 1,15 for reinforcing and prestressing steel. For reduction of partial safety factors, Annex C of EN 13369:2004 shall apply. 4.3.3.3.4 Section and member design The following aspects shall be taken into account: a) Internal forces and moments In multiple slats with at least one intermediate transversal connection, it may be assumed that loads acting at the crossings of longitudinal beams and transversal connections are distributed over the various beams as if the connections have infinitely great stiffness. This may be assumed only on the condition that the cross sectional area of the connections equals at least 0,85 times the cross sectional area of the beams, and that the upper and lower reinforcement bars of the connections possess satisfactory anchorage. The torsional stiffness may only be taken into account when the torsional stresses are checked and taken on by reinforcement. b) Ultimate limit state The shear reinforcement of floor slats may be omitted on the condition that the design value of the applied shear force is not greater than the design shear resistance of the section of a slat without shear reinforcement. c) Serviceability limit state Design in the serviceability limit state shall include the following limit states: 1) Cracking
