Research and Application of Health Monitoring System for Special-shaped Concrete-filled Steel Tube Arch Bridge

摘要

Bridge structural health monitoring system is very necessary to master operational condition, ensure safety of structure, detect damage and conduct effective maintenance. Based on the health monitoring system design of a irregular shaped concrete-filled steel tube arch bridge, this paper elaborates on the design principles of health monitoring system, and introduces the layout proposal of all kinds of sensors on the bridge and the matching collection system and software system. The practice may provide reference for the health monitoring system of long-span bridges.
