Which of the following relation is correct for design wind speed (Vz) and basic wind speed (Vb) ?(a) Vz ∝ Vb^2(b) Vz ∝ 1/Vb^2(c) Vz ∝ Vb(d) Vz ∝ 1/VbThis question was posed to me during an internship interview.This interesting question is from Determination of Wind Loads & Load Combinations in chapter Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer»

The correct ANSWER is (c) Vz ∝ Vb

The BEST I can explain: Vz = k1k2k3Vb , where k1=probability factor(risk coefficient), k2=terrain, HEIGHT and STRUCTURE size factor, k3=topography factor.
