US-PRC Collaborative Research on Innovative Design and Implementation of Semi-Active and Passive Energy Dissipation Systems for Seismically Excited Civil Infrastructures

该项目已提交给“性能、安全和减灾研究的结构控制”竞赛。本研究将与中华人民共和国哈尔滨大学的专家合作进行，该项目的目标是：对基于地震和风激结构控制理论的各种被动耗能系统的设计进行理论和实验研究；开展理论和实验研究，开发一种新的半主动保护系统，称为半主动液压动量阻尼器系统（SAHMDS）；并在中国西南某大型建筑中安装和测试被动式液压动量阻尼器系统（HMDS）。前两项任务将主要在尔湾进行，最后一项任务将在中国进行，两个小组将共同努力。这种安排的好处是，在过去十年中，中国专家已经安装了一些地震激发土木结构的被动控制系统，并进行了研究，可以与美国同行分享他们的经验。这些系统将进行地震和风力减灾测试。* * *

9625616 Yang This project was submitted to the "Structural Control for Performance, Safety and Hazard Mitigation Research" competition. The research will be conducted in cooperation with experts from the Harbin University, PRC, and the objectives of the project are: to conduct both theoretical and experimental studies for the design of various passive energy dissipation systems based on control theories for seismic- and wind- excited structures; to carry out theoretical and experimental studies for the development of a new semi-active protective system, referred to as the semi- active hydraulic momentum damper system (SAHMDS); and to install and test a passive hydraulic momentum damper system (HMDS) in a full scale building in South West China. The first two tasks will be carried out mainly at Irvine and the last in PRC with both groups working together. The benefit of this arrangement is that during the last decade some passive control systems for seismically excited civil structures have been installed and studies by Chinese experts who can share their experiences with the American counterpart. These systems will be tested for seismic and wind hazards mitigation. ***
