［摘要］对仅设置多道竖向槽钢加劲肋的钢板剪力墙承受轴向压应力的情况，进行了大量有限元弹性屈曲分析，得到了轴向压应力随加劲肋抗弯刚度和加劲肋抗扭刚度变化的曲线，以及加劲板的临界应力等于小区格按简支计算的轴压屈曲临界应力条件下加劲肋双面布置时加劲肋的门槛刚度。在加劲肋刚度小于门槛刚度时给出了钢板剪力墙弹性轴压屈曲临界应力与加劲肋刚度的关系。将双面加劲同单面加劲、交错加劲两种情况进行比较，得出了后两者的门槛刚度放大系数。与数值计算结果的比较表明，公式具有良好的精度，并且公式结果均在安全一侧。

Abstract: The elastic buckling of steel plate shear walls vertically stiffened by channels is investigated under axial compression, and the curves of relating axial compressive buckling stresses to flexural and torsional rigidities of stiffeners are presented. Threshold rigidities are presented on stiffeners determined by the demand that the critical axial compressive stresses be equal to the buckling stress of simply supported sub-panel. In case that the rigidities of stiffeners are less than the threshold stiffness, a formula is proposed relating the buckling stress to the rigidities of stiffeners. Plates stiffened by channels on one side or stiffened by channels on one side alternately on both sides of the plate are analyzed, and compared with both sides stiffeners. Modification factor is proposed for the threshold stiffness.

Keywords: steel plate shear wall; axial compressive stress; channel; stiffener; threshold stiffness; elastic buckling
