摘　　要：基于大型通用软件ANSYS,分析了6种加劲肋参数下的钢柱弹性屈曲特性,由分析结果得到了加劲肋的厚度越大,对腹板的约束越大,并有效的提升了钢柱腹板的一阶临界屈曲应力系数,120 mm宽的加劲肋由于自由伸出长度过大,会发生过早的屈曲,而导致腹板屈曲失效。Based on the large common software ANSYS, this paper analyzes the characteristics of six kinds of elastic buckling of steel columns stiffener parameters by analyzing the results the following conclusions： stiffener thickness, the greater the constraints on the web, and effectively enhance the steel column web＇s first critical buckling stress factor, 120 mm wide stiffeners due to the free extended length is too large, buckling occurs prematurely, resulting in buckling failure.

关 键 词：加劲钢柱 腹板屈曲 纵向加劲肋 临界屈曲应力系数
