US/PRC Joint Research Program in Structural Control

9402196 Soong与中国研究人员的联合研究计划的目标是全面实施被动和主动控制技术，以对抗风和地震荷载。 虽然中国的几个结构正在考虑进行结构控制，但该项目的重点是南京大厦，它不仅被选为控制实施，而且还被选为安装多个系统的试验台，并对其性能进行观察，分析和比较。 在该项目的第一阶段，将与中国的研究人员合作，为南京中心大厦进行合适的控制系统的研究、开发和安装。 所考虑的系统包括调谐液体阻尼器，粘弹性阻尼器，调谐，半主动和混合质量阻尼器。 从这个联合研究项目中获得的结构控制研究界的直接利益之一是有关结构控制的一些重要实施问题的新信息。该项目第二阶段要解决的一些问题包括：系统优化、故障安全措施、可靠性和维护、操作问题、诊断和成本效益分析。 ***

9402196 Soong The objective of this joint research program with researchers in PRC is the full-scale implementation of passive and active control technology to structures against wind and earthquake loads. While several structures in PRC are being considered for structural control, the focus of the project is on the Nanjing Tower, which has been chosen not only for control implementation but also as a test-bed where multiple systems will be installed and their performances observed, analysized and compared. During the first phase of this project the research, development and installation of suitable control systems for the Nanjing Tower will be carried out in collaboration with PRC researchers. The systems under consideration include tuned liquid dampers, viscoelastic dampers, and tuned, semi- active, and hybrid mass dampers. One of the direct benefits to the structural control research community derived from this joint research program is new information about some of the important implementational issues in connection with structural control. Some of the issues to be addressed in the second phase of this project include: system optimization, fail- safe measures, reliability and maintenance, operational issues, diagnostics, and cost benefit analysis. ***
