ABSTRACT This research demonstrates the efficacy of 2–4 viscous dampers in self-centering rocking structures with bi‑linear elastic response, which is distinctly different to conventional fixed‑base structures. This study assesses the relative impact of 2–4 devices versus typical viscous dampers and 1–3 viscous devices. Performance is assessed by maximum displacement, total base shear, and maximum acceleration, which are indicative of structural, foundation and contents demand. Simultaneous reductions of displacement, base-shear and acceleration are only available with the 2–4 damper. Finally, a simple method is proposed to incorporate 2–4 viscous dampers into self‑centering systems using standard design approaches.

具有 2-4 个粘性阻尼器的自定心系统的抗震性能

摘要 本研究证明了 2-4 个粘性阻尼器在具有双线性弹性响应的自定心摇摆结构中的功效，这与传统的固定底座结构明显不同。本研究评估了 2-4 个设备与典型粘性阻尼器和 1-3 个粘性设备的相对影响。性能通过最大位移、总基础剪切和最大加速度进行评估，这些指标表明结构、基础和内容需求。位移、基础剪切和加速度的同时减少仅适用于 2-4 阻尼器。最后，提出了一种使用标准设计方法将 2-4 个粘性阻尼器纳入自定心系统的简单方法。
