ENV 1991-2-4. If this standard does not set out any requirements, the wind pressure shall be taken in accordance with national standards and requirements; c) the wind pressure acts as a uniformly distributed load over the total slope length /* of the span and may be reduced in accordance with equation (3): β.qq=red (3) where: qred is the reduced wind pressure acting on the slope length l* of the span; β is the reduction coefficient; q is the wind pressure in accordance with (2). The reduction coefficient is determined as a function of the slope length l* of the span as follows:  for l* ≤ 200 m β = 1,0;  for l* ≥ 900 m β = 0,65;  for intermediate values of l*, β is determined by linear interpolation.

 action due to wind in accordance with 6.5.4 ; actions due to ice taken as 0,4 times the value in 6.5.5.2;  action due to ice in accordance with 6.5.5.2; action due to wind taken as 0,8 times the value in 6.5.4. 2) out of operation:  action due to wind in accordance with 6.5.4; actions due to ice taken as 0,4 times the value in 6.5.5.2;  action due to ice in accordance with 6.5.5.2; action due to wind taken as 0,6 times the value in 6.5.4. For these 2 cases "out of operation", the value of wind according to 6.5.4 can be reduced by the factor 0,65. 7.3 Tension safety factor - General For the calculation of the tension safety factor, the supplier and operator may agree to use the test breaking force in place of the minimum breaking force.
