Design moments M

where

M = moment from 1st order analysis e,NEd = effect of imperfections where e = i0 / 400

e0NEd = minimum eccentricity where e0 = h / 30 > 20 mm

MEdyy = 95.7 + (3570 / 400) x 8933 x 10-3 > 0.02 x 8933 = 95.7 + 79.7 > 178.7 = 175.4 < 178.7 kNm MEd22 = 18.8 + 79.7 > 178.7

However, imperfections need only be taken in one direction - where they have the most unfavourable effect .'. use MEd22 = 178.7 with MEdyy = 95.7 kNm.
