Faced with the rapid development of structural control technologies in the field of civil engineering, building design philosophy has been changing its traditional concept. However, in the current stage, active control of structures is still under development and hence not for ensuring the safety during large earthquakes. One of the major purposes of this research is to construct an intelligent control system which can work even in case of large earthquake. To do this, two systems are demonstrated to have their promising possibilities : one is a hybrid control system combining variable gain-based active mass damper (AMD) with hysteretic damper and the other is a semi-active system utilizing variable friction damper.For the purpose of constructing an appropriate reduced model for controlled high-rise building structures, the concept of model reduction for a controlled structure is presented and the effectiveness of the control system design based on such a concept is demonstrated.

面对土木工程领域结构控制技术的飞速发展，建筑设计理念也在不断改变其传统观念。然而，在目前阶段，主动控制结构仍处于发展阶段，因此不能保证大地震时的安全。本研究的主要目的之一是构建一个即使在大地震情况下也能工作的智能控制系统。为了做到这一点，两种系统被证明具有很好的可能性：一种是结合基于可变增益的主动质量阻尼器（AMD）和滞后阻尼器的混合控制系统，另一种是利用可变摩擦阻尼器的半主动系统。为了建立合适的高层建筑结构受控模型简化模型，提出了受控结构模型简化的概念，并验证了基于该概念的控制系统设计的有效性。
