Hybrid Control of Building Seismic Response Using Architectural Cladding

将覆层-结构相互作用提供的被动阻尼与鲁棒性相结合的混合控制系统的实验和分析研究本项目将实施主动控制系统。在研究建筑中用作被动耗能和刚度的先进覆层连接系统方面积累的经验增强系统将在这次调查中发挥作用。研究计划分为五个主要任务：(1)使用覆层作为被动控制系统；(2)经典、现代、稳健和脉冲控制在建筑中的应用：(3)可能的混合控制系统的发展；(4)性能评估；(5)模型实验(以及未来测试计划)。这项研究将由一个跨学科的研究小组进行，他们将积极和实际地参与地震工程和广泛的具有开发和应用鲁棒控制理论的经验。拟议的多学科小组成员之间的互动将涉及动态建模(包括不确定性建模)领域，与被动和主动阻尼的相对程度相关的权衡研究，以及实验验证。预计总体研究工作的结果将有助于：(1)建筑结构(主动和被动)稳健控制的创新方法，以及(2)将工程被动减振系统与现代鲁棒控制器相结合的创新方法，以实现实际建筑控制可应用于地震和其他动态加载条件的系统。

Experimental and analytical investigations of hybrid control systems designed to combine passive damping provided by cladding- structure interaction with robust active control systems will be conducted in this project. Experienced gained in the study of advanced cladding connection systems designed to be employed in buildings as passive energy dissipation and stiffness augmentation systems will be put to advantage in this investigation. The research plan is organized into five primary tasks: (1) Use of cladding as a passive control system; (2) Application of classical, modern, robust and pulse control to buildings; (3) Development of possible hybrid control systems; (4) Performance evaluation; and (5) Model experiments (and plans for future testing). The research will be carried out by an interdisciplinary team of researchers that combines active and practical involvement in earthquake engineering with broad experience in the development and application of robust control theory. Interaction among the proposed multidisciplinary team members will be in the areas of dynamic modelling (including modelling of uncertainties), trade- off studies related to the relative degrees of passive versus active damping, and experimental validation. Results of the overall research effort are expected to contribute: (1) innovative approaches to robust control of building structures (both active and passive), and (2) innovative methods for combining engineered passive damping systems with modern robust controllers to achieve practice building control systems that can be applied to earthquake and other dynamic loading conditions.
