scope:

This European standard defines the loading, the relevant loadmodel positions and the internal forces acting on noise barriers,due to the air pressure wave set out in EN 1991-2:2003, 6.6.2. Thevertical and horizontal shapes of the air pressure wave and thedynamic effects have been taken into account. The calculationmethod described in this European standard has been developed fornoise barriers having a post-and-panel structure with piledfoundations. It can also be used where cladding is attached to arigid structure. For structures with piled foundations, anempirical formula for determination of the natural frequency isgiven in Annex A. Annex B contains an example of application of thecalculation method for determination of internal forces and momentsacting on a mid-post. The design of noise barriers (e.g. to fatigueresistance) is not part of this standard.
