Question

Which of the following relation between design pressure, pz and design wind speed, Vz  is correct?

(a) pz ∝ Vz^2

(b) pz ∝ 1/Vz^2

(c) pz ∝ Vz

(d) pz ∝ 1/Vz

I got this question during an online exam.

I'd like to ask this question from Determination of Wind Loads & Load Combinations topic in section Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer 1

Correct choice is (a) pz ∝ Vz^2

For explanation I would say: pz = 0.6Vz^2, where pz is in N/m^2 and Vz  is in m/s. 0.6 factor depends on number of factors and mainly on atmospheric pressure and air temperature.
