A reduction factor Cr, to load carrying capacity for a long column of effective length Le and width b is applied as obtained from the following expression:
1
\(1 - \frac{{{L_e}}}{{24b}}\)
2
\(1.25 - \frac{{{L_e}}}{{36b}}\)
3
\(1.25 - \frac{{{L_e}}}{{48b}}\)
4
\(1.5 - \frac{{{L_e}}}{{60b}}\)
5
\(1.25 - \frac{{{L_e}}}{{48}}\)
