ABSTRACT
In an attempt to capture the influence of each individual width ratio on the column elastic distortional post-critical strength, Figure 2(b) depicts the variations of P10t/Pcr with each of the bw/bf , bw/t and bf /bl width ratios, while keeping the remaining two constant. The analysis of this limited amount of results suggests that:
(i) By far the best documented P10t /Pcr variations are those associated with the bw /bf ratio, which involve the C 60(6)/75/80(6)/90/100/110(2)/116/ 118/120(7)/ 130 columns – bw/bf varies between 1.0 and 2.0, while bw/t = 40 and bf /bl = 7.50 are kept constant. The variation of P10t/Pcr with bw/bf follow roughly ascending straight line.
