摘要 为了研究板件中间加劲的复杂卷边槽钢轴压构件畸变屈曲临界应力的简便计算方法,应用有限条分析软件CUFSM对冷弯薄壁板件中间加劲的复杂卷边槽钢以及腹板中间V型加劲的复杂卷边槽钢共90个轴压构件进行数值模拟,分析各参数对构件弹性畸变屈曲临界应力的影响。经拟合分析,得出针对板件中间加劲的复杂卷边槽钢、腹板中间V型加劲的复杂卷边槽钢轴压构件的弹性畸变屈曲临界应力的简化计算公式,并验证该公式的有效性。 In order to investigate the simplified calculative method of channels with complex edge stiffeners for the elastic distortional buckling stress under axial compressive load , a total of 90 cold-formed thin-walled steel channels with web stiffeners and complex edge stiffeners , channels with complex edge stiffeners and intermediate V type stiffeners in the web were analyzed by finite strip software CUFSM .The influence of the parameters for the elastic distortional buckling stress was analyzed .Simplified formulas for calculating the elastic distortional buckling stress of web stiffeners and complex edge stiffeners , channels with complex edge stiffeners and intermediate V type stiffeners in the web under axial compressive load were provided .The availability of the formulas was verified .
