摘　　要：为研究一种工程应用中的复杂十字形截面钢柱受力性能,文章采用Abaqus软件建立了十字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:该类十字形截面柱具有较好的延性和良好的耗能能力,结构的塑性变形区域主要集中在端部;并根据研究结果提出了相关设计建议。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 by using Abaqus software.The mechanical properties of the steel column under different loading modes were investigated by analyzing the changes of the failure forms,lateral stiffness changes,skeleton curves,ductility properties and other key parameters.The results show that this kind of cross section column has good ductility and good energy dissipation,and the plastic deformation area of the structure is mainly at the gradual end.Based on the research results,some design suggestions are put forward.
