项目摘要

This reports presents a study on the development of seismic testing techniques with selflearning capabilities. First, a review on the development of seismic testing techniques was conducted to identify the limitations overlying the present seismic testing techniques. This review indicates that two of the testing techniques that promise further enhancement of seismic research are the on-line test using the substructuring techniques and the realtime on-line test. To realize the on-line test using the substructuring techniques, a new integration technique was devised, by which the test can be implemented without the constraint of numerical stability associated with substructuring. A on-line test system that uses conventional testing devices was developed, and the integration technique devised was incorporated into the system. Using the test system, a 10 story building structure combined with hysteretic dampers was tested for its earthquake response. In the test, a representative hysteretic damper was tested, individual hysteretic dampers were modeled with the aid of the self-learning capabilities incorporates into the system, the main frame of the structure was modeled a priori, and the entire structure was analyzed in use of the substructuring techniqes. The test results demonstrate the effectiveness of the integration technique and self-learning capabilities devised and the overall power of the on-line test using the substructuring techniques. Finally, a feasibility study was carried out for the real-time on-line test, in which digital signal processors were used for ensuring fast data creation and transfer.

本文对具有自学习能力的地震测试技术的发展进行了研究。首先，对地震测试技术的发展进行了回顾，找出了现有地震测试技术的局限性。本文指出，有希望进一步加强地震研究的两种测试技术是使用子结构技术的在线测试和实时在线测试。为了实现用子结构技术进行在线测试，设计了一种新的积分技术，该技术可以实现不受子结构技术数值稳定性约束的测试。开发了一种使用常规测试设备的在线测试系统，并将所设计的集成技术融入到系统中。利用该试验系统，对一座10层结构加滞回阻尼器的结构进行了地震反应试验。在试验中，测试了一个典型的滞回阻尼器，利用系统的自学习能力对单个滞回阻尼器进行了建模，对结构的主框架进行了先验建模，并使用子结构技术对整个结构进行了分析。测试结果证明了所设计的集成技术和自学习能力的有效性，以及使用子结构技术进行在线测试的整体能力。最后，对实时在线测试的可行性进行了研究，采用数字信号处理器来保证数据的快速创建和传输。
