Steel plate shear walls in this paper consist of X-shaped restrainers, embedded steel plates and boundary restrainers (simply referred to as XSPSW). The XSPSW was constrained by sliding X-shaped restrainers. The embedded steel plate was divided into diagonally arranged square sub-plates with small height-to-thickness ratio by X-shaped restrainers set on two sides of the embedded steel plate. Shear buckling of the plate can effectively be constrained, and the seismic energy dissipation capacity of the SPSW can be increased. Moreover, because the external X-shaped restrainers have characteristics of rapid assembly and high stiffness, they can be reused after a rare earthquake. Four groups of quasi-static experiments on unreinforced steel plate shear walls (USPSWs) and XSPSWs were conducted to obtain their mechanical properties and energy dissipation capacity. The failure mechanism of the XSPSW under cyclic load was revealed, and the rationality of the XSPSW was verified. Experimental results showed that the initial stiffness, load-carrying capacity, and energy dissipation capacity of the XSPSWs were at least 21%, 11%, and 27%, respectively, higher than those of the USPSW. For USPSWs, the embedded steel plate with a small height-to-thickness ratio exhibited relatively stable hysteretic performance. The height-to-thickness ratio of the subplate is the main factor affecting the hysteretic performance of the XSPSW. Meanwhile, the X-shaped restrainers were not damaged during the experiment and could be reused.

本文中的钢板剪力墙由X形限制器，嵌入式钢板和边界限制器（简称XSPSW）组成。XSPSW受滑动X形约束器约束。通过设在埋入钢板两侧的X形限制器，将埋入钢板分成高度/厚度比小的对角排列的正方形子板。可以有效地限制板的剪切屈曲，并且可以增加SPSW的地震能量消散能力。此外，由于外部的X形限位器具有装配迅速和高刚度的特点，因此在发生罕见地震后可以重新使用。进行了四组在无筋钢板剪力墙（USPSWs）和XSPSWs上的准静态实验，以获得其力学性能和能量耗散能力。揭示了XSPSW在循环载荷作用下的失效机理，并验证了其合理性。实验结果表明，XSPSW的初始刚度，承载能力和能量耗散能力分别比USPSW高出至少21％，11％和27％。对于USPSW，高厚比小的嵌入式钢板表现出相对稳定的磁滞性能。底板的高厚比是影响XSPSW滞后性能的主要因素。同时，X形限制器在实验过程中没有损坏，可以重复使用。揭示了XSPSW在循环载荷作用下的失效机理，并验证了其合理性。实验结果表明，XSPSW的初始刚度，承载能力和能量耗散能力分别比USPSW高出至少21％，11％和27％。对于USPSW，高厚比小的嵌入式钢板表现出相对稳定的磁滞性能。底板的高厚比是影响XSPSW滞后性能的主要因素。同时，X形限制器在实验过程中没有损坏，可以重复使用。揭示了XSPSW在循环载荷作用下的失效机理，并验证了其合理性。实验结果表明，XSPSW的初始刚度，承载能力和能量耗散能力分别比USPSW高出至少21％，11％和27％。对于USPSW，高厚比小的嵌入式钢板表现出相对稳定的磁滞性能。底板的高厚比是影响XSPSW滞后性能的主要因素。同时，X形限制器在实验过程中没有损坏，可以重复使用。XSPSW的能耗分别比USPSW高出至少21％，11％和27％。对于USPSW，高厚比小的嵌入式钢板表现出相对稳定的磁滞性能。底板的高厚比是影响XSPSW滞后性能的主要因素。同时，X形限制器在实验过程中没有损坏，可以重复使用。XSPSW的能耗分别比USPSW高出至少21％，11％和27％。对于USPSW，高厚比小的嵌入式钢板表现出相对稳定的磁滞性能。底板的高厚比是影响XSPSW滞后性能的主要因素。同时，X形限制器在实验过程中没有损坏，可以重复使用。
