Abstract
The bending response characteristics of ten tubes subjected to axial pre-compressive stresses ranging from 0 to 45 % of the tube wall yielding stress (σr) were investigated experimentally. The tubes had different diameter-to-thickness ratios of 42 and 56 and length-to-diameter ratios of 15 and 20. The results showed up to a 31 % reduction in the bending capacity of tubes when σr increased from 0 to 45 %. Experimental interaction diagrams for axial pre-compression and bending moment capacity were compared with the proposed relationships in different codes, with the results showing a substantial load-bearing capacity of tubes beyond the codes' predictions.
