Wind Load Eurocode 1
Calculation note for wind Load according to eurocode.
Eurocode 1: Action on structures - Part 1-4 - Wind Actions (EN-1994-1-4)
Peak Velocity Pressure
1 Determine basic wind velocity [Vb]
2 Determine mean wind velocity [Vm]
3 Determine roughness factor
4 Determine wind turbulence [Iv(Z)]
5 Determine peak velocity prerssure [qp(Z)]
6 Determine wind pressure acting on external surfaces [We]
7 Determine wind pressure acting on the internal surfaces [Wi]
8 Determine wind force (Fw) acting on a structural component
9 Determine wind force Fw acting on structure through vectorial summation of:
(a) External forces: Fw,e = CsCd ∑We Aref
(b) Internal forces: Fw,i = ∑Wi Aref
(c) Frictional forces: Ffr = Cfr qp (Ze) Afr
10 Determination of CsCd(a)the structure corresponds to one of the general shapes shown below
