Health monitoring system for a self-anchored suspension bridge

摘要

Automatic measurement of instrumented civil engineering structures is becoming more commonfor behaviour monitoring during construction in field as well as long-term monitoring for life time assessment.The considerations for deploying a proper monitoring system are appropriate instrumentation, reliable signalprocessing and intelligent information processing This paper addresses general guidelines and suggestion regardingthe main elements of structural monitoring as mentioned. This paper also presents a structural monitoringapplication considering these three issues on a self-anchored suspension bridge, Yongjong Bridge, which wasconstructed on the new freeway between Seoul and New International Airport in Inchon. Sensor and hardwareinstrumentation, signal transmission, signal acquisition and analysis are schematically described.
