Full-Scale Active Control Research and Implementation

本项目涉及大型主动控制结构系统的研究、开发、设计和实现。在过去的20年里，土木工程结构在环境荷载下的主动控制进行了大量的分析和实验工作。现在的进展是这样的，大规模实施是可行的。近年来，全尺寸原型系统已经在日本建成并进行了测试，但到目前为止，美国还没有对这项重要的新技术进行全面的研究和先进的系统开发。该系统包括一个150英尺高的塔式研究结构，将在俄亥俄州阿克伦的国家发明家名人堂组装。该塔将能够通过(i)模拟地震，（ii）自然风和（iii）通过机械手段进行其他类型的运动来进行动态激励。设计将是灵活的，允许塔的动态特性和控制配置为研究用途而变化。并将纳入功能，使最先进的主动控制技术得到开发和测试。该项目将由一个以工业和学术为基础的合作研究团队进行。

This project concerns research, development, design and implementation of a large-scale active control structural system. Considerable analytical and experimental works have been carried out in active control of civil engineering structures under environmental loads over the past 20 years, and now the progress is such that large-scale implementation is feasible. Full-scale prototype systems have been built and tested in Japan in recent years, but no full-scale research and state-of- the-art system of this important new technology in the U.S. has been developed to date. The proposed system comprises a 150- foot high tower research structure to be assembled at the National Inventor's Hall of Fame in Akron, Ohio. The tower will be capable of dynamic excitations by (i) simulated earthquakes, (ii) natural winds, and (iii) other types of motions by mechanical means. The design will be flexible, permitting the dynamic properties and control configuration of the tower to be varied for research use, and will incorporate features to enable state-of-the-art active control techniques to be developed and tested. The project will be carried out by a collaborative industrial and academic based research team.
