【摘要】 本文针对卷边对冷弯薄壁槽钢轴压柱屈曲性能的影响进行了研究,采用有限元软件ABAQUS分析了简单卷边、向内复杂卷边和向外复杂卷边槽钢柱的屈曲性能,对翼缘宽度、腹板高度和壁厚等参数对构件稳定性的影响进行了参数分析。研究表明在一些情况下带复杂卷边构件可以有效地提高构件的屈曲应力。更多还原

【Abstract】 The effects of edge stiffeners on the buckling behaviors of the cold-formed thin-walled C columns are studied in this paper. The buckling behaviors of C columns with simple lip stiffeners, inside and outside angled stiffeners, inside and outside hook stiffeners are analyzed by means of ABAQUS. The effects of the sizes of the flange and web and the thickness on the buckling behaviors of C columns are discussed. The buckling stresses of the C columns with the complex stiffeners are higher than those with simple lip stiffeners in some cases.更多还原
