Eccentricity due to Imperfections

Eccentricity due to Imperfections
ei = θi · l02
θi = θ0 · αh  · αm
θ0 = 1200
23  αh = 2l 1
αm = 0.5 · ( 1+ 1m )
ei eccentricity due to imperfections
θi overall inclination of structure
θ0 basis value recommended by NA
αh reduction coefficient relating to length
αm reduction coefficient relating to number of elements where m is number of vertical elements contributing to total effect
