  Wind EN1991-1-4

  How to Calculate Wind Actions in Accordance with Eurocode 1 (Flowchart)

  
  

  Fundamental basic wind velocity

  ↓

  Basic wind velocity [V_b,0] ← Direction factor [C_dir], Seasonal factor [C_season]

  ↓

  Mean wind velocity [V_b] ← Roughness factor [c_r(z)], Orography factor [c_0(z)]

  ↓

  Peak velocity pressure [q_p(z)] ← Turbulence intensity [I_v(z)], Air density [ρ]

  ↓

  Wind pressure external surfaces [W_e] ← Pressure coefficient external [c_pe]

  ↓

  Wind pressure internal surfaces [W_i] ← Pressure coefficient internal [c_pi]

  ↓

  Wind force [F_w] ←Structure coefficient [c_sc_d], Force or pressure coefficient
