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 the number of elements, where m is number of vertical elements contributing to the total effect
