本文研究了设置1道横向板条加劲肋以及1～4道竖向槽钢加劲肋的钢板剪力墙在纯剪作用下的弹性屈曲,研究中着重考虑了横肋和竖肋之间的相互作用.以加劲钢板墙在纯剪作用下的临界剪应力等于小区格的屈曲应力为条件,得到一系列反映横肋和竖肋相互关系的曲线.分析表明钢板墙所需的横肋的门槛刚度随着竖肋加劲系数的增加而减小,且在竖肋加劲系数不变的条件下,随着竖肋扭转约束的增强而减小.根据计算结果提出了能够考虑横肋和竖肋相互作用的加劲肋门槛刚度的计算公式,与数值结果比较,表明公式具有良好的精度.%This paper presented an investigation on the elastic buckling of stiffened steel plate shear walls in shear,with 1 flat-bar horizontal stiffener and 1～4 channel section vertical stiffeners.In the study,the interaction between the vertical and horizontal stiffeners was considered.By making the buckling stress of the SSPW equal to that of the sub-panel surrounded by stiffeners and edges, a se-ries of curves were obtained revealing the relationship between vertical and horizontal stiffeners.The results indicate that the threshold stiffness of the horizontal stiffener is affected by the width-to-height ratio of subpanel,the bending stiffness of vertical stiffener and the torsional stiffness of the vertical stiffener.Solutions are also proposed for the threshold stiffness of the horizontal stiffener.Compared with the predictions of the proposed solutions and the finite element results indicate good accuracy of the proposed solutions.
