EN 40-3-1:2013 (E) 3 Foreword This document (EN 40-3-1:2013) has been prepared by Technical Committee CEN/TC 50 “Lighting columns”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by August 2013, and conflicting national standards shall be withdrawn at the latest by August 2013. Attention is drawn to the 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 supersedes EN 40-3-1:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. There are seven parts to the series of standards EN 40 - Lighting columns, as follows  Part 1: Definitions and terms;  Part 2 : General requirements and dimensions;  Part 3: Design and verification:  Part 3-1: Specification for characteristic loads;  Part 3-2: Verification by testing;  Part 3-3: Verification by calculation;  Part 4: Requirements for reinforced and prestressed concrete lighting columns,  Part 5: Requirements for steel lighting columns;  Part 6: Requirements for aluminium lighting columns;  Part 7: Requirements for fibre reinforced polymer composite lighting columns. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Scope This European Standard specifies design loads for lighting columns. It applies to lighting columns of nominal height (including any bracket) not exceeding 20 m. Special structural designs to permit the attachment of signs, overhead wires, etc. are not covered by this European Standard. The requirements for lighting columns made from materials other than concrete, steel, aluminium or fibre reinforced polymer composite (for example wood, plastic and cast iron) are not specifically covered in this standard. Fibre reinforced polymer composite lighting columns are covered in this document, in conjunction with Annex B of EN 40-7:2002. This European Standard includes performance requirements for horizontal loads due to wind. Passive safety and the behaviour of a lighting column under the impact of a vehicle are not addressed. Such lighting columns will have additional requirements (see EN 12767). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Wind pressures 5.2.1
General The characteristic wind pressure q(z), in N/m2, for any particular height above the ground, z, shall be obtained from the following formula: q(z) = δ× β× f×ce(z)×q(10) (1) where q(10) given in 5.2.2, is the reference wind pressure. δ given in 5.2.3, is a factor related to the column size. β given in 5.2.4, is a factor dependent on the dynamic behaviour of the column. f given in 5.2.5, is a factor related to topography. ce(z) given in 5.2.6, is a factor dependent on the terrain of the site and the height above the ground, z. NOTE 1 q(10), f and ce(z), are based on the principles given in EN 1991-1-4. SIST EN 40-3-1:2013
