摘　　要：在屈曲约束钢板墙受力机理研究的基础上,利用理论分析方法对两边连接屈曲约束钢板墙的屈服承载力和初始刚度进行了研究,提出了屈服承载力和初始刚度的计算公式,分析得到了钢板墙横截面剪应力不均匀分布系数的变化范围并给出了建议计算公式和取值。利用建议计算公式对不同高度和不同宽度的两边连接屈曲约束钢板墙进行了计算分析,并与有限元方法和已有公式的计算结果进行了对比验证。对比表明本文建议计算公式相比其他公式形式简单,计算方便,具有更高的精度。Based on the research about stressing mechanism of buckling restrained steel plate shear wall（BRSPSW）,yielding capacity and initial stiffness of buckling restrained steel plate shear wall with two-side connections are studied using theoretical method. The formulas to calculate yielding capacity and initial stiffness are presented. Furthermore,the changing range,proposed formula and proposed value of shearing stress distribution factor for buckling restrained steel plate shear wall are analyzed. Then buckling restrained steel plate shear walls with different height and different width are analyzed using proposed formulas,finite element method and other formulas. The results indicate that the proposed formulas are simpler but have more accuracy.
