U.S.-Japan Cooperative Research: Structural Control of Smart Civil Infrastructure Systems

9314853 Housner该奖项支持加州大学地震工程研究(CUREe)George Housner教授和大阪大学建筑工程系Yutaka Inoue教授之间为期两年的合作研究项目。该奖项支持美国结构控制研究小组的美国科学家前往日本与日本同行小组会面，以规划、协调、促进和开展民用基础设施系统监测和控制领域的研究。双方的共同努力还将提供一份详细的研究议程，为未来的美日合作研究项目奠定基础。结构地震反应的主动控制可以描述为对建筑物或土木结构在未知外部地震扰动作用下的动力响应进行逐一修正的系统。这是通过提供控制力来抵消地震运动，或者通过改变结构的动力特性来减少地面震动的影响来实现的。为了实现上述目标，必须建立构成地震控制基础的理论和分析方法，并需要一个全面的逐步研究计划，以检验各种关于结构性能和实际应用的方法和系统。指导和协调这一领域的研究，这是有效研发计划的关键要求。美日在不断交换信息方面的合作将带来新的发展和研究方向。***

9314853 Housner This award supports a two-year cooperative research project between Professor George Housner, California Universities for Research in Earthquake Engineering (CUREe), and Professor Yutaka Inoue, Department of Architectural Engineering, Osaka University. The award supports the travel of U.S. scientists on the U.S. Panel on Structural Control Research to Japan to meet with the counterpart Japanese panel to plan, coordinate, promote, and conduct research in the field of monitoring and control of civil infrastructure systems. The joint efforts will also provide a detailed research agenda that will be the foundation for future U.S.-Japan cooperative research projects. The active control of seismic response of structures can be described as a system to modify from one instant to the next the dynamic responses in buildings or civil structures induced by an unknown external seismic disturbance. This is accomplished by providing control forces to counteract the seismic motions, or by changing the dynamic properties of the structure so as to reduce the effect of the ground shaking. To achieve the foregoing, the theory and analytical methods that will form the basis of seismic control must be established, and a comprehensive step-by-step research program is necessary to examine various methods and systems regarding performance and practical application to structures. Direction and coordination of research in this field in a key requirement for an effective R&D program. U.S.-Japan cooperation in a continuing exchange of information will lead to new developments and directions for research. ***
