Ehdotuksen tiedot

EN 1991-1-4 gives principles and rules for the determination of natural wind actions for the structural design of building and civil engineering works for each of the loaded areas under consideration. This includes the whole structure or parts of the structure or elements attached to the structure, e.g. components, cladding units and their fixings, safety and noise barriers. This part is applicable to: - buildings and civil engineering works with heights up to 300m; - bridges having no span greater than 200m. This part is intended to predict characteristic wind actions on land-based structures, their components and appendages. This part is also applicable to structures less than 1km offshore from the main coastline. For offshore structures more than 1km from the main coastline, the terrain effects defined in this part do not apply.
