摘　　要：利用ANSYS有限元软件分析了T形钢异形柱框架节点在单调和循环荷载作用下的基本力学性能,对软件分析得出的节点应力分布规律进行了初步分析。结果表明,异形柱节点的节点域处受力复杂,在弹性阶段其应力比梁上应力更大。还研究了翼缘和腹板宽厚比对节点滞回性能的影响,得出了建设性的结论,并提出了节点的滞回模型。Basic mechanical property of frame joint with T specially shaped column was analysed with the ANSYS computer finite program,including the distribution of stress,the results show that the stress in the middle of the connection is much higher than that of the beam before it goes into elastic stage.And the influence of width-thickness ratios of flange and web on hysteretic behavior of joints was also researched,and some useful results were got,a hysteretic model of connections was put forward.

关 键 词：T形钢异形柱 框架节点 滞回性能
