Critical Threehold Value for Monitoring & Management of Cable Tension Force in Cable-Stayed Bridge

Abstract

This paper presents a methodology for the probabilistic determination of managing criteria for cable tension force monitoring in cable-stayed bridges using acceleration data acquired by the monitoring system. There are many long span bridges installed with monitoring system in the world. The monitoring systems are installed to diagnose abnormal behavior or damage in bridges and to warn it to bridge management agency. In cable-stayed bridges, the cable tension force could be an important indicator of abnormal behavior
