DIN EN 40-3-1:2013-06 EN 40-3-1:2013 (E) 4 1 Scope This European Standard specifies design loads for lighting columns. It applies to lighting
25、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
26、 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 requiremen
27、ts 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 ref

35、lar height above the ground, z, shall be obtained from the following formula: q(z)= fce(z)q(10) (1) where q(10) given in 5.2.2, is the reference wind pressure. given in 5.2.3, is a factor related to the column size. given in 5.2.4, is a factor dependent on the dynamic behaviour of the column. f give
36、n 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. DIN EN 40-3-1:2013-06 EN 40-3-1:2013 (E) 6 NOTE 2 The procedure above,
37、 using and factors, is intended as a simplified procedure that will offer a conservative approach. 5.2.2 Reference wind pressure q(10) The value of q(10) (in N/m) accounts for the geographical location of the lighting column. It is derived from the reference wind velocity Vref(in m/s) using the foll
38、owing formula: q(10) = 0,5(Cs)2Vref2 (2) where Vrefis the 10 minute mean wind velocity at 10 m above ground level for terrain category II (see Table 1) having an annual probability of exceedence of 0,02 (commonly referred to as having a mean return period of 50 years). Vref= CALTVref,0Vref,ois the b
39、asic value of the reference wind velocity at 10 m above sea level obtained from the wind maps referred to in Annex A; CALTis an altitude factor to be taken as 1,0 unless otherwise recommended in the National Annex to EN 1991-1-4 is the air density. The air density is affected by altitude and depends
40、 on the temperature and pressure to be expected at the site location during wind storms. The value of shall be taken as 1.25 kg/m3, unless otherwise recommended in the National Annex to EN 1991-1-4. Csis a factor to convert Vreffrom an annual probability of exceedence of 0,02 to other probabilities,
41、 and can be derived from the formula given in Annex A. For lighting columns the normal requirement is for a mean return period of 25 years, for which the factor Csshould be taken as .,9205.2.3 Factor for column size The greater the size of a surface subject to wind, the more unlikely it is that the
42、maximum pressure, on which the calculation is based, acts over its full area. The resultant smaller wind load on a component is taken into account by the factor dependent on the size of the area. The ruling dimension for the size of the area subject to the wind is the greatest dimension in one direc
43、tion. For a lighting column, this is the nominal height in metres. The value of the factor shall be obtained from the formula: = 1 - 0,01 h 5.2.4 Factor for the dynamic behaviour of lighting columns, The factor is dependent upon the basic period of vibration T and the damping of the “column/luminair
44、e“ system and takes into account the increase in the load, resulting from the dynamic behaviour of the lighting column, caused by wind gusts. DIN EN 40-3-1:2013-06 EN 40-3-1:2013 (E) 7 The period of vibration T in seconds for the determination of in accordance with Figure 1 shall be obtained either
45、by calculation or by testing.

46、05144T3- 0.22793T2+ 0.67262T 5.2.5 Topography factor f The topography factor f shall be taken as 1, unless topography is specified as significant. Where a topographic feature is significant, the methodology in EN 1991-1-4:2005, Annex A should be used. The altitude used for calculating CALTshall be t
47、he altitude at the base of the topography slope in the upwind direction. 5.2.6 Exposure coefficient ce(z) The exposure coefficient accounts for variation of wind pressure with respect to height above ground and depends on terrain category. The appropriate terrain category for the location of the lig
48、hting column shall be decided on the basis of Table 1. DIN EN 40-3-1:2013-06 EN 40-3-1:2013 (E) 8 Table 1 Description of terrain category Category Description I Rough open sea.
