摘　　要：《钢结构设计规范》（GB50017—2003）认为单轴对称的T型钢轴心压杆绕对称轴的稳定性是弯扭失稳问题。本次试验发现，剖分T型钢轴压杆有必要做弯扭屈曲验算，计算方法采用换算长系比法。The stability about struts of monosymmetric section built with cut T - shape column is flexural torsional hackling in the Code for Design of Steel Structures （GB50017 -2003 ）. Tests indicate that cut T - shape column subject to compression need to be checked on flexural torsional backling. The approach of equivalent slenderness ration is recommended for calculation purpose.

关 键 词：剖分T型钢 弯扭屈曲 稳定 换算长细比
