Wind loading

conform EN1991-1-4

Wind tunnel study to determine wind loading on buildings.

Wind loading and wind-induced dynamic response of tall buildings have significant effect on their structural safety, therefore, it is important to know the amount of loading building needs to withstand. This can be determined either by following the calculation procedure outlined in Eurocode EN1991-1-4 or by using wind tunnel testing. Wind tunnel testing provides an advantage as the testing procedure is not limited to only simple geometries but can handle complex building shapes and surroundings.

Wind tunnel testing compliant with EN1991-1-4

In cases where cladding loads, structural loads or a dynamic response of a building needs to be determined Actiflow offers a wind tunnel study carried out by an external institution. The study is fully compliant with EN1991-1-4 while taking into account requirements outlined in relevant National Annex. The wind tunnel testing is carried out for 36 wind directions (in 10° increments) and can provide data at up to 320 points on a building. Results can be delivered in a form of cladding pressures, structural loads, or pressure coefficients.
