摘　　要：国内外对钢板剪力墙的研究较少考虑竖向荷载的影响,这与工程实际不符。为准确估算钢板剪力墙承受竖向荷载后的弹性屈曲性能,对四边简支,两侧边固支、上下边简支和四边固支矩形钢板剪力墙在剪压作用下的弹性稳定性能进行有限元分析。根据有限元计算结果,修正不同边界条件钢板剪力墙剪压荷载下的相关屈曲计算公式,与有限元结果比较表明,修正后的公式具有较高精度,可以在钢板剪力墙的设计中应用。The steel plate shear wall is studied with shear load considered only,which isn＇t accord with the engineering practice.To evaluate the elastic buckling strength of steel plate shear wall bearing shear and vertical load accurately,a finite element analysis is carried out to investigate the elastic buckling of steel plate shear wall with simply surpport on four sides,fix surpport on two vertical sides and simply surport on others and fix support on four sides under shear and pressure.Based on FEA data,the interaction equations of shear combined with vertical compression are revised.Comparisons of the calculation results with those of FEA show that the revised equations have good accuracy and can be applied to design steel plate shear wall.
