The Butterfly-shaped Link Steel Plate Shear Wall as a novel lateral resisting system is proposed and experimentally investigated. In this system, by creating the peripheral Butterfly-shaped links in the web plate, the lateral load resisting mechanism is determined by the shear strength of the links. The geometric attributes of the links are effective parameters for predicting the values of stiffness and strength of the proposed system, as investigated in this paper. To fulfill this aim, four experimental specimens with different geometric parameters containing the taper, slenderness, and width ratios are constructed. The samples are loaded by using the cyclic loading protocol to investigate the behavior of the system. The experimental results confirm that the link dominant limit state controls the stiffness, strength, and ductility of the specimens. The Butterfly-shaped link geometry with the dominant shear limit state results in higher stiffness and strength, and the link geometry with a dominant flexural limit state shows the higher ductility. Besides, the hysteresis diagram of specimens shows the optimal ductility and high energy dissipation even at low drifts. Then, by numerical modeling verification, Butterfly-shaped Links Steel Plate Shear Wall with the restrained web plate is intended to improve the cyclic behavior. The principal purpose of the numerical study is to investigate the restrainer's impact on the energy dissipation capacity of the samples. The results show that the out-of-plane instability is reduced, the pinching phenomena eliminated, and the dissipated energy of the specimens is increased considerably by the web plate restraining.

提出了蝶形连杆钢板剪力墙作为新型的侧向抵抗体系，并进行了实验研究。在该系统中，通过在腹板中创建周边的蝴蝶形链节，抵抗横向载荷的机制由链节的抗剪强度决定。链节的几何属性是预测所提出系统的刚度和强度值的有效参数，正如本文所研究的那样。为了实现这一目标，构建了四个具有不同几何参数的实验样品，这些参数包括锥度，细长度和宽度比。通过使用循环加载协议加载样本以调查系统的行为。实验结果证实，链接支配极限状态控制着刚度，强度，和标本的延展性。具有主要剪切极限状态的蝴蝶形链节几何形状具有较高的刚度和强度，具有主要弯曲极限状态的链节几何形状具有较高的延展性。此外，样品的磁滞图显示了最佳的延展性和高能量耗散，即使在低漂移时也是如此。然后，通过数值模型验证，带有约束腹板的蝴蝶形连接钢板剪力墙旨在改善循环性能。数值研究的主要目的是研究限制器对样品能量消散能力的影响。结果表明，通过腹板约束，减少了平面外的不稳定性，消除了夹捏现象，并大大增加了样品的耗散能量。具有主要剪切极限状态的蝴蝶形链节几何形状具有较高的刚度和强度，具有主要弯曲极限状态的链节几何形状具有较高的延展性。此外，样品的磁滞图显示了最佳的延展性和高能量耗散，即使在低漂移时也是如此。然后，通过数值模型验证，带有约束腹板的蝴蝶形连接钢板剪力墙旨在改善循环性能。数值研究的主要目的是研究限制器对样品能量消散能力的影响。结果表明，通过腹板约束，减小了平面外的不稳定性，消除了夹捏现象，并大大增加了样品的耗散能量。具有主要剪切极限状态的蝴蝶形链节几何形状具有较高的刚度和强度，具有主要弯曲极限状态的链节几何形状具有较高的延展性。此外，样品的磁滞图显示了最佳的延展性和高能量耗散，即使在低漂移时也是如此。然后，通过数值模型验证，带有约束腹板的蝴蝶形连接钢板剪力墙旨在改善循环性能。数值研究的主要目的是研究限制器对样品能量消散能力的影响。结果表明，通过腹板约束，减少了平面外的不稳定性，消除了夹捏现象，并大大增加了样品的耗散能量。
