U.S.-Japan Cooperative Research on Structural Control

主动结构反应控制技术在土木工程和建筑工程领域取得了显著的发展。在1988年召开的第九届世界地震工程会议上，报告和讨论了结构反应控制的最新研究成果，引起了许多研究人员和工程师对反应控制技术的极大兴趣。结构主动响应控制的主要目标是减小地震或大风等不确定动力扰动引起的响应。土木工程和建筑结构中的主动控制系统主要是利用作动器产生的控制力的类型或具有改变结构特性(如刚度或阻尼性)的装置的类型。这些材料是在…上积累的更多的数据来源于日本和美国合作研究小组自1994年开始的调查数据库。最新的数据库被系统地安排在几个物理目标上：控制定理、控制装置和实际应用的系统设计。通过由日本和美国研究人员组成的研究项目组的详细调查和讨论，发布了针对每个研究目标的最新报告。收集了1994年1月17日北岭地震和1995年1月17日Hyogoken南方地震期间安装结构控制装置的建筑物的地震反应数据。然后，通过对比观测和分析数据，研究了这些受控建筑结构在地震作用下的行为特征。1996年3月，美日结构控制合作研究研讨会在京都/日本举行。本次研修班与向日本科学促进会提交的研究项目《大地震智能结构控制的发展》密切相关。该项目的首席研究员和研究人员主要策划和管理研讨会。在研讨会期间，与会者考察了京都大学防灾研究所的真实尺寸结构控制试验设施，并就创新结构控制系统的开发交换了信息。日本和美国的研究人员报告了主动控制的最新进展。内容选自1996年6月举行的第11届世界地震工程大会“结构的主动控制”专题会议。在此基础上提出了新的发展方向。1996年12月，作为这项工作的一个项目，组织了第二届国际结构控制研讨会，总结了《建筑控制》、《桥梁控制》、《健康监测》、《控制案例研究》和《控制规范的设计哲学》。较少

Remarkable developments of active structural response control technology have been made in civil and architectural engineering fields. In the 9th World Conference on Earthquake Engineering (9WCEE) held in 1988, recent studies for structural response control were reported and discussed, and a great interest in response control technology arose in many researchers and engineers. The main objective of active response control of structures is the reduction of response induced by uncertain dynamic disturbances such as earthquakes or strong winds. Actively controlled systems in civil and building structures are mainly the type using control force generated by actuators or the type with devices for changing structural characteristics such as stiffness or damping.To start this research project, updating and rearrangements of databases for recent studies of response control technology in the mechanical, civil and architectural engineering fields, were carried out. These materials were accumulat … More ed from databases based on investigations by cooperative research group of Japan and the U.S.started since 1994. Most recent databases are arranged systematically on several physical objectives : control theorem, control device and system design for practical applications. State-of-Art-Report for each research objective was published through detailed investigations and discussions by research project groups composed from researchers of Japan and the U.S.Earthquake response data of the buildings equipped with structural control devices during Northridge Earthquake in January 17,1994 and Hyogoken Nanbu Earthquake in January 17,1995, was collected. Then, characteristics of behavior of these controlled building structures during earthquakes were studied by comparing observational and analytical data. In March, 1996, U.S.-Japan workshop in cooperative research on structural control were held in Kyoto/Japan. This workshop is closely related with the research program "Development of Intelligent Structural Control for Large Earthquakes" which was submitted to the Japanese Society for the Promotion of Science. The Principal Investigator and researchers of this program mainly planned and managed the workshop. During the workshop, the participants inspected the real size structural control test facilities at Disaster Prevention Research Institute, Kyoto University, and exchanged information on development of innovative structural control systems.Recent developments concerning active control are reported both by Japanese and U.S.researchers. The contents were selected from special theme session of "Active Control of Stuctures" in the 11th World Conference of Earthquake Engineering (11WCEE) held in June, 1996. Then, a new direction was proposed. In December, 1996, the 2nd international workshop of structural control was organized as a program of this work, and summarizes "Building Control", "Bridge Control", "Health Monitoring", "Case Studies of Control" and "Design Philosophy of Control Codes".
