摘要/Abstract

摘要： 为进一步了解帽形加劲复杂卷边槽钢柱的受力性能，利用ANSYS有限元分析软件对帽形加劲复杂卷边槽钢柱在轴压和偏压状态下的稳定性能进行分析.研究了立柱长度、板件宽厚比、截面类型以及偏心距对帽形加劲复杂卷边槽钢柱的稳定承载力、破坏模式及变形等性能的影响.研究结果表明: 在板件厚度不变时，C2截面构件的承载效率相比C1截面构件提高了10%~20%，C3截面构件相比C1截面构件提高了40%~50%.腹板帽形加劲复杂卷边槽钢柱的承载力最大发生在负偏心一侧，而腹板及翼缘帽形加劲复杂卷边槽钢柱在正偏心处承载力最大.

Abstract: In order to further understand the mechanical behavior of the channel columns with complex edge stiffeners and cap shaped stiffeners，the stability of channel columns under axial and eccentric compressive loading was studied by the finite element program called ANSYS. Effects of specimen length， the width to thickness ratio of plate， section types and the eccentric distance on stability，buckling mode and deflection behavior of channel columns with complex edge stiffeners and cap shaped stiffeners were investigated.The results show that under the same condition，the bearing capacity of members with section C2 is 10%~20% larger than that of C1， and the bearing capacity of members with section C3 is 40%~50% larger than that of C1. When it comes to the maximum load， the channel column with cap shaped stiffener on web takes on negative eccentricity， while the channel column with cap shaped stiffener on both web and flange takes on positive eccentricity.

Key words: channel with complex edge stiffeners, element with cap shaped stiffeners, finite element analysis, eccentricity, stability behavior
