| Abstract: |
Owing to progressively increased demands of high-strength steels (e.g. S460, S690 and S960) in steel construction, an experimental program was developed to study welded box-section steel columns under compression accounting for residual stress distribution. In this paper, a series of numerical analyses were performed to identify the effect of residual stress on the overall buckling loads of the welded box-section columns. At the end of the study, it was observed that residual stress distribution has little influence on the overall buckling loads of the welded box-section steel columns. It was also observed that dimensional properties and residual stress ratio α/β have a minor and a significant influence respectively on the overall stability coefficient of welded box-section steel columns. |
