There have been national comments proposing to include the effect of n in the slenderness limit. These proposals were rejected until and including the October 2001 draft, referring to figure 5.8 and the disagreement concerning the 10%-criterion. However, as can be seen from figures 5.10 and 5.11, with different end moments there is a strong reduction of the slenderness limit with increasing normal force, and that is true for both 10%-criteria. The only exception is when criterion 2 is applied to columns with equal end moments, see figure 5.10.

5.8.3.1.4 Comparisons with previous model for slenderness limit

In tables 5.3 and 5.4, values from tables 5.1 and 5.2 are compared with values according to the slenderness criterion in the October 2001 draft (expression 5.13):

Xim = 25- (ro + 0,9)- (2 - M01/M02) In both cases the 10 % criterion is according to alternative 1.
