摘　　要：为避免对四边连接屈曲约束钢板墙在连接处首先发生破坏,提出在屈曲约束钢板墙上错列开洞使塑性应变主要分布在钢板墙内部,并通过形成斜向拉力带和压力带保证屈曲约束钢板墙具有较好的材料利用效率。利用理论分析方法对四边连接开洞屈曲约束钢板墙的屈服荷载和初始刚度进行了研究,提出屈服荷载和初始刚度的计算公式,公式形式简单、计算方便,与有限元分析结果的对比表明计算结果具有较高的精度。In order to avoid the damage of four-side connected buckling restrained steel plate shear wall occurred first at the connection with boundary elements, staggered holes in four-side connected buckling restrained steel plate shear wall is proposed to ensure the plastic strain mainly distribute inside the steel plate. Furthermore, the forming of inclined tension and compression bands can also ensure good material efficiency of the steel plate. Then, yielding capacity and initial stiffness of holed buckling restrained steel plate shear wall with four-side connections are studied using theoretical method. The formulas of yielding capacity and initial stiffness are proposed. The proposed formulas are simple and convenient to use, and the accuracy is validated by finite element analysis results.
