Annex A: Wind pressure versus Wind force 85 Scaffolding In paragraph “6. Load cases” the wind has been calculated with EN1991-1-4 and calculated as a wind pressure. Following EN 12810-1, it is also possible to calculate the wind as a wind force using the following formula (EN 12810-1, (1)): = ∙ ∙ ∙ With Ai is the reference area specified in EN 12810-1, Table 4 (see also below) cf is the aerodynamic force coefficient taken from EN 12810-1, Table 5 (see also below) cs is the site coefficient taken from EN 12810-1, Table 6 (see also below) qi is the design velocity pressure in accordance with EN 12810-1, Figure 3: In this example, the height of the structure is 11m, so qi on 11m is + 940 N/m² and on 0m + 800 N/m². When inserting one value a average of those two can be taken: 870 N/m². The reference Area Ai: Cladding condition of the system configuration Reference area Ai Unclad Area of each component projected in the wind direction Clad Surface area of the cladding (see A.3 of En 12811-1:2003) This example was an unclad example. For a component with a diameter of 48,3mm, the area is 0,0483m x Lcomponent. The aerodynamic force coefficient cf : Cladding condition of the system configuration Force coefficient Normal to the façade Parallel to the façade Unclad 1,3 1,3 Clad 1,3 0,1
