Wind pressure acting normal to individual is element or claddity unit is _________(a) F = [ (Cpe – Cpi)A/pd].(b) F = [ (Cpe + Cpi)A/pd].(c) F = [ (Cpe – Cpi)Apd].(d) F = [ (Cpe – Cpi)/Apd].I got this question in quiz.This interesting question is from Determination of Earthquake Loads topic in section Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer»

The correct answer is (C) F = [ (Cpe – Cpi)APD].

BEST EXPLANATION: F = (Cpe – Cpi)A pd , where F=net wind force on element, Cpi= internal pressure coefficient, Cpe=external pressure coefficient,A=surface area of element, pd=design wind pressure.
