Abstract
Wireless sensors have been proposed for use in structural health monitoring systems because they offer low-installation costs and automated data processing functionality. To validate the performance of the proposed WiMMS (wireless modular monitoring system) on the vibration measurement of large-scale civil structures, a three-story half-scale steel structure is instrumented with a wireless monitoring system assembled from a network of six wireless sensors and tested it on a shaking table to ensure the reliability of the data communication. Field application of WiMMS to ambient vibration survey of Gi-Lu cable-stayed bridge is investigated. Finally, the preliminary study on structural control using MR-damper through WiMMS is also presented.
There are five chapters in this report.
The Chapter1 includes the overview of this research and introduction.
In Chapter2, a detail introduction of wireless sensing unit is discussed.
In Chapter3, it is focus on integrating the wireless sensing unit with traditional sensing system. There are two experiments in this chapter, the health monitoring of benchmark 3F steel structure and the ambient vibration measuring on Gi-Lu Bridge.
Chapter4 includes the applying wireless sensing unit on structure control. In this chapter, a new action board is designed for structure control and new embedded software is designed for centralized control and decentralized control.
Finally, Chapter5 is the conclusion of this research. It includes the results of applying wireless technology of civil engineering and the future work of this research.
