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

小行星9314853 该奖项支持加州大学地震工程研究所（CUREE）的乔治豪斯纳教授与大坂大学建筑工程系的井上丰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，以计划，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。 联合努力还将提供一个详细的研究议程，这将是未来美国的基础。日本合作研究项目。 结构地震反应的主动控制可以描述为一个系统，以修改从一个瞬间到下一个由未知的外部地震扰动引起的建筑物或民用结构的动力反应。 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态特性来减少地面震动的影响来实现的。 为了实现上述目标，必须建立地震控制基础的理论和分析方法，并且需要一个全面的逐步研究计划，以检查有关性能和实际应用于结构的各种方法和系统。 指导和协调该领域的研究是有效研发计划的关键要求。 美国--日本在不断交流信息方面的合作将导致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. ***
