近年来，在抗震设计中提出了各种控制摇摆系统，以防止损伤集中，并实现对输入地震动强度范围宽的自定心。然而，在将其应用于实际建筑物之前，还有几个障碍需要克服，例如对大型自定心后张（PT）钢绞线的要求以及对抗拔柱底座的特殊处理。本文提出了一种无PT钢绞线耗能构件的无上拔脊柱框架体系，其自中心功能依赖于包络弹性框架。该系统被应用到一个实际的建筑在日本建造。将传统的剪切阻尼器和以往研究中开发的PT钢绞线上抬摇摆系统应用于同一建筑结构，通过数值模拟，对3种系统的损伤分布、耗能、自定心、抗震鲁棒性和不规则刚度等性能进行了比较和讨论。
Recently, various controlled rocking systems have been proposed in seismic design to prevent damage concentration and to achieve self-centering against a wide range of input ground motion intensities. However, there are several obstacles to overcome before they can be applied to actual buildings, such as the requirement of large, self-centering post-tensioned (PT) strands and special treatment at uplift column bases. This paper proposes a non-uplifting spine frame system with energy-dissipating members without PT strands; its self-centering function relies on envelope elastic moment frames. The system is applied to an actual building constructed in Japan. Conventional shear damper and uplifting rocking systems with PT strands developed in prior studies are applied to the same building structures, and the performance of the three systems, including damage distribution, energy dissipation, self-centering, robustness against severe earthquake, and irregular stiffness, is compared and discussed through numerical simulations.
