Monitoring results of a self-anchored suspension bridge

Abstract

Automatic measurement of instrumented civil engineering structures is now widely applied for behavior monitoring during construction in field as well as long-term monitoring for lifetime assessment of bridge structures. This paper presents schematically the monitoring system installed in Yeongjong Bridge, a self-anchored suspension bridge located in the expressway linking Seoul and Incheon International Airport. Since (1) appropriate instrumentation, (2) reliable signal processing and (3) intelligent information processing constitute the major features to be considered for deploying proper monitoring system, corresponding general guidelines and suggestions are also proposed. In addition, a representative example of results that can be acquired through structural health monitoring system is presented by means of data measured during 2 years after the opening of the bridge. © 2005 Springer.
