方钢管-焊接T形钢组合截面柱轴压整体稳定性
Axial Compression Global Stability of Square Steel Tube-Welded T-Shaped Steel Composite Section Columns
摘要
Abstract
To investigate the influence of initial geometric imperfections and residual stresses on the global stability of square steel tube-welded T-shaped steel composite section columns with different steel strengths and normalized slenderness ratios,a model was established using ABAQUS software.By varying the steel strength,initial geometric imperfections,residual stresses,and normalized slenderness ratios of the components,the global stability performance of the square steel tube-welded T-shaped steel composite section columns was analyzed.The results indicate that residual stresses have the greatest impact on the global stability performance of the components;as the steel strength increases,the stability of the components improves;with an increase in the normalized slenderness ratio,the influence of initial geometric imperfections and residual stresses on the global stability of the components decreases.关键词
