This European Standard shall be given the sta
16、tus 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of an identical text or by endorsement, at the latest by August 2013, and conflicting national standards shall be withdrawn at the latest by August 2013.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 subj
17、ect of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 40-3-3:2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. There are se
18、ven 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 calc
19、ulation; 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 Int
20、ernal 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,
21、Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 40-3-3:2013EN 40-3-3:2013 (E) 4 1 Scope This European Standard specifies the requirements for the verification of
22、 the design of lighting columns by calculation. 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 col
23、umns 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 standard in conjunction with EN 40-7.
24、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). The calculations used in this Euro
25、pean Standard are based on limit state principles, where the effects of factored loads are compared with the relevant resistance of the structure. Two limit states are considered: a) the ultimate limit state, which corresponds to the load-carrying capacity of the lighting column; b) the serviceabili
26、ty limit state, which relates to the deflection of the lighting column in service. NOTE In following this approach, simplifications appropriate to lighting columns have been adopted. These are: 1) the calculations are applicable to circular and regular octagonal cross-sections; 2) the number of sepa
27、rate partial safety factors have been reduced to a minimum; 3) serviceability partial safety factors have a value equal to unity. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

40、6.2.3.2 5 Structural strength requirements (ultimate limit state) 5.1 Application of calculations The adequacy of the strength of the lighting column shall be calculated for the following cross sections: a) the point at which the column is fixed (normally at ground level); b) the lower edge of the d
41、oor opening. If the positions of the door and the brackets can be changed relative to each other and are not specified, the lower edge of the door opening should be calculated about its weakest axis. If two or more door openings are provided, the strength of each opening shall be verified (see Figur
42、e 1); c) in addition to b) for tapered lighting columns the top of the door opening. If two or more door openings are provided, the strength of each opening shall be verified (see Figure 1); d) the point at which the bracket begins if the column and the bracket consist of one piece, or the point at
43、which the bracket is attached if the bracket is detachable and check the junction between the bracket arm and the column; e) transition from one diameter to another or at a change in material thickness; f) anti-rotation device between the columns and the bracket arm, if such a device is present and
44、intended to transfer torsional forces between the bracket arm and the column; g) any other critical position. 5.2 Characteristic loads The characteristic loads for strength requirements shall be calculated in accordance with EN 40-3-1. BS EN 40-3-3:2013EN 40-3-3:2013 (E) 7 5.3 Characteristic strengt
45、h of materials 5.3.1 Metal lighting columns The characteristic yield strength fy,in N/mm2, of steel and aluminium alloys shall be calculated in accordance with EN 1993-1-1 and EN 1999-1-1 respectively. The increase in yield strength due to any process (such as cold working) shall not be used for mem
46、bers which are subject to another process (such as heat treatment or welding) which may result in softening. 5.3.2 Concrete lighting columns The characteristic strength shall be determined in accordance with EN 40-4. 5.3.3 Fibre reinforced polymer composite lighting columns The characteristic streng
47、th shall be determined in accordance with EN 40-7. 5.4 Design loads The characteristic loads specified in 5.2 shall be multiplied by the appropriate partial load factors, fshown in Table 1 to give the design load to be used for the ultimate limit state calculation.

49、ctively, shall be calculated for each position specified in 5.1 using the design loads specified in 5.4. For cross-sections with openings the x-x and y-y axes shall be taken as shown in Figures 5b and 6. NOTE For regular octagonal cross-sections the axes can be positioned through the centre of the flat side or through a corner. For closed regular cross-sections, the bending moments Mxand Mymay be combined to give a single moment, Mp,in Nm, that gives the most adverse action on the column cross-section being considered a
