近年来，结构控制装置的研究和发展受到了相当大的关注，特别强调减轻建筑物和桥梁的风和地震反应。在这两个领域，人们都在认真努力，把结构控制的概念发展成一种可行的技术，今天，我们已经在各种各样的结构中安装了许多这样的装置。本文的重点是被动和主动结构控制系统。被动系统包括一系列用于增强结构阻尼、刚度和强度的材料和装置。主动系统包括主动系统、混合系统和半主动系统，它们采用集成了传感器、控制器和实时信息处理的可控力装置。本文包括其发展的简要历史概述，以及对这种令人兴奋且仍在发展的技术的最新技术和实践的评估。还包括在讨论中的优点和局限性的背景下，抗震设计和改造的土木工程结构。(C)2002爱思唯尔科技有限公司版权所有。
In recent years, considerable attention has been paid to research and development of structural control devices, with particular emphasis on alleviation of wind and seismic response of buildings and bridges. In both areas, serious efforts have been undertaken to develop the structural control concept into a workable technology, and today we have many such devices installed in a wide variety of structures. The focus of this state-of-the-art paper is on passive and active structural control systems. Passive systems encompass a range of materials and devices for enhancing structural damping, stiffness and strength. Active systems, which include active, hybrid and semi-active systems, employ controllable force devices integrated with sensors, controllers and real-time information processing. This paper includes a brief historical outline of their development and an assessment of the state-of-the-art and state-of-the-practice of this exciting, and still evolving, technology. Also included in the discussion are their advantages and limitations in the context of seismic design and retrofit of civil engineering structures. (C) 2002 Elsevier Science Ltd. All rights reserved.
