First order bending moments with imperfection

The calculation of first order moment is calculated only for Member type = Column and it in case, that columnis in compression see,"Determination whether member is in compression" and it runs according to the following procedure:

• first order eccentricity without effect of imperfection is calculated,
• eccentricity caused by imperfection is calculated ,
• first order eccentricity including effect of imperfection is calculated.
