| Abstract: |
In this paper, the test results of the column under combined loading conditions are reported. The shallow I-shaped steel section that is typical for the column was selected for the specimen. The section’s width-thickness ratio is compact (class 1), and a ductile behaviour can be expected. The axial force level and slenderness ratio were the testing parameters, and 11 specimens were prepared. The testing found that most specimens achieved full-plastic bending moment capacity even if they did not fulfil the design requirements. On the other hand, some specimens did not reach the ductility shown in the design recommendation. Lateral torsional buckling was the dominant failure mode; however, the ultimate limit state that was determined by Pd-effects was also confirmed from the testing. Finally, a design recommendation that is not stipulated in the current design recommendation is proposed. |
