US/PRC Joint Research Program in Structural Control

9402196宋这项与中国研究人员的联合研究计划的目标是全面实施结构的被动和主动控制技术，以抵御风和地震荷载。虽然我国目前正在考虑将几种结构用于结构控制，但本项目的重点是南京塔，它不仅被选为控制实施的对象，而且还被选为一个试验台，将安装多个系统，并对其性能进行观察、分析和比较。在该项目的第一阶段，将与中国研究人员合作，研究、开发和安装适合南京塔的控制系统。正在考虑的系统包括调谐液体阻尼器、粘弹性阻尼器和调谐、半主动和混合质量阻尼器。这一联合研究计划给结构控制研究界带来的直接好处之一是关于与结构控制有关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. ***
