GPS application for structural health monitoring on a cable-stayed bridge
Automatic measurement of instrumented civil engineering structures is becoming more common for both diagnostic system identification purpose and in-field behavior monitoring during construction. In order to deploy a successful monitoring system, the required considerations are: proper instrumentation, reliable signal processing and knowledgeable information processing. Since instrumentation, which includes sensory device and data acquisition system, obtains raw data from the real structure, sensor technology is of critical importance in the development of a monitoring system. A number of sensor and sensing techniques have been developed in recent years which bear the potential for meeting the eventual need of an automatic monitoring system. These fall into the domain of remote sensing and nondestructive testing. Selection and installation of proper sensors constitute key considerations. GPS (Global Positioning System) has been considered one of the emerging sensing technologies for measuring static and dynamic behavior of the bridges, due to the reliability, durability and precision. This paper presents the result of feasibility study for to apply GPS for measuring dynamic characteristics which would be used for structural health monitoring on a cable-stayed bridge.
