摘　　要：在前人研究基础上,通过施加多道具有抗扭刚度的竖向槽钢加劲肋,然后再加1道没有抗扭刚度的横向板条加劲肋,对双面双向加劲的钢板剪力墙进行大量有限元弹性屈曲分析,最后提出钢板剪力墙弹性屈曲临界剪切应力和加劲肋门槛刚度的计算公式。数值计算结果表明:公式具有良好的精度,并且偏安全;影响加劲肋门槛刚度的关键因素是钢板剪力墙小区格宽高比、竖肋数目以及横竖肋板厚比。Based on previous studies , the vertical channel stiffeners with torsional rigidity are first installed , then one transverse strip stiffener with no torsional rigidity is installed , numerous SPSWs with cross double-sided stiffeners are analyzed with finite element elastic buckling analysis method , formulas are presented to calculate SPSWs ’ shear buckling critical stress and stiffeners ’ threshold rigidity .The results of calculations show that , the accuracy of the formulas is good and they are reasonably conservative;key factors affecting stiffeners ’ threshold rigidity are aspect ratio of panel ,the number of vertical stiffener and thickness ratio of vertical and transverse stiffeners .
