摘　　要：为研究一种工程应用中的复杂T字异形截面钢柱受力性能,文章采用ABAQUS软件建立了T字异形截面钢柱的有限元模型,通过分析构件的破坏形式、侧向刚度变化、骨架曲线、延性性能等关键参数的变化,探究在不同加载方式下该异形截面钢柱的受力性能。分析结果表明:该类T形截面柱在沿Z轴方向进行加载时,其耗能性能相对较弱,延性相对较差,结构塑性区域主要发生在距离柱脚一定高度处。In order to study the mechanical properties of a complex T-shaped steel column in engineering applications,the finite element model of the T-shaped steel column was established with ABAQUS software.The mechanical properties of the special steel column under different loading modes were investigated by analyzing the changes of key parameters,such as the failure form,lateral stiffness,skeleton curve and ductility of the components.The analysis results show that the energy dissipation and ductility of T-section columns are relatively weak when they are loaded along the Z axis,and the plastic area of the structure mainly occurs at a certain height from the column foot.
