摘　　要：为解决钢板剪力墙难以应用国内规范设计的问题,采用有限元软件ANSYS对钢板剪力墙在剪切荷载作用下的弹塑性屈曲性能进行分析,系统比较初始缺陷、宽高比和高厚比等参数对钢板剪力墙弹塑性屈曲性能的影响,提出衡量弹塑性屈曲性能的合理参数。通过数值模拟,并结合现有规范,提出钢板剪力墙弹塑性稳定的实用设计公式。与有限元计算结果的比较表明,该公式精度良好,且便于应用。It is difficult to design SPSW （ steel plate shear wall ） for Chinese current design code .To solve this problem, the finite element software ANSYS was applied to analyze the elastic-plastic buckling behavior under the shear force.The influences of parameters, such as initial imperfection, width to height ratio and width to thickness ratio, on the elastic-plastic buckling of SPSW were compared .According to the results of the analysis , the rational parameter to evaluate the elastic-plastic buckling behavior of SPSW was presented .Based on the FEA data and Chinese current design codes , formulas, used to calculate elastic-plastic instability of SPSW, were fitted. Comparisons with the numerical results showed that the proposed formulas had good accuracy and could be applied in practical engineering .
