The steel plate shear wall (SPSW) with two-side connections can be arranged flexibly in the structure, and has no additional influence on the column, but its buckling capacity is difficult to be deduced directly by thin plate theory. The low yield point SPSW (LYP-SPSW) with two-side connections is proposed in this paper, including unstiffened LYP-SPSW, cross-stiffened LYP-SPSW and diagonally-stiffened LYP-SPSW. The elastic buckling performance and buckling capacity of these three types of LYP-SPSWs are studied by numerical simulation. On the basis of the accurate model, a series of parametric analysis on the key factors were conducted, including the height-to-thickness ratio, the stiffness ratio of the stiffener, and the stiffness ratio of the edge member, which have effects on the elastic buckling stress of the LYP-SPSW with two-side connections. The elastic buckling stress of the SPSW can be effectively increased by adding stiffeners and edge members, but it is unnecessary to use oversized stiffeners and edge members. Based on a large amount of parametric analysis, simplified formulas for calculating the elastic buckling stresses of the three types of LYP-SPSWs mentioned above are proposed in this paper.

两侧连接的钢板剪力墙（SPSW）可以灵活地布置在结构中，并且对立柱没有附加影响，但是其屈曲能力很难通过薄板理论直接推导。本文提出了一种具有两侧连接的低屈服点SPSW（LYP-SPSW），包括未加劲的LYP-SPSW，交叉加劲的LYP-SPSW和对角加劲的LYP-SPSW。通过数值模拟研究了这三种类型的LYP-SPSW的弹性屈曲性能和屈曲能力。在精确模型的基础上，对关键因素进行了一系列的参数分析，包括高/厚比，加劲肋的刚度比和边缘构件的刚度比，这些因素都会影响到两侧连接的LYP-SPSW的弹性屈曲应力。通过添加加劲肋和边缘构件可以有效地增加SPSW的弹性屈曲应力，但是不必使用超大的加劲肋和边缘构件。在大量参数分析的基础上，提出了计算上述三种类型的LYP-SPSWs弹性屈曲应力的简化公式。
