Active control has been applied to base-isolated buildings to achieve high control performance. A base-isolated building with active control has many design parameters, such as parameters of the superstructure, isolator, viscous dampers, and hysteretic dampers. The conventional control-system design uses trial-and-error approaches to select these design parameters and numerical simulations to estimate the responses of the system, causing a limited design outlook. In this study, we presented a spectrum-based design method for active base-isolated buildings with both viscous and hysteretic dampers for selecting the parameters of the isolator, viscous damper, steel hysteretic damper, and controller. The presented method estimates the maximum responses and maximum control force of the control system only using response spectra of the design earthquake wave, thus eliminating trial-and-error approaches and numerical simulations. Numerical design examples were also used to show the details of the design procedure and the validity of the presented method.

主动控制已应用于基础隔离建筑物，以实现高控制性能。具有主动控制的基础隔震建筑具有许多设计参数，例如上部结构、隔震器、粘滞阻尼器和滞回阻尼器的参数。传统的控制系统设计使用试错法来选择这些设计参数和数值模拟来估计系统的响应，导致设计前景有限。在这项研究中，我们提出了一种基于谱的设计方法，用于具有粘性和滞回阻尼器的主动式基础隔震建筑，用于选择隔振器、粘性阻尼器、钢滞回阻尼器和控制器的参数。所提出的方法仅使用设计地震波的响应谱来估计控制系统的最大响应和最大控制力，从而消除了试错法和数值模拟。数值设计实例也被用来展示设计过程的细节和所提出方法的有效性。
