ωk=βzμsμzω0
(6. 1. 1)
formula
ωk- standard value of wind load, kn/m2;
Wind vibration coefficient of βz-z height;
μ s shape coefficient of wind load;
μ z-wind pressure height variation coefficient;
ω0- basic wind pressure value, kN/m2.
The basic wind pressure is to leave the ground on the local relatively empty and flat ground.

υ0 (m/s) as the standard, press
ω 0 = υ 02/ 1600 to determine the wind pressure value.
Basic wind pressure shall not be less than
0.25 kn/m2.
