Structure Health Monitoring System of a Noval Steel-Free Cable Stayed Bridge

Steel and concrete are the main buiding material of the civil engineering community, but with its easily errosion behaviour and CO2 discharge, it should be substituded with new materials.Fiber reiforcement polymer (FRP) is such a developped material, with its high strength to weight ratio, durability prolongation, hight stiffness to weight ratio and its fatigue resistance behaviour, it is now getting widely used in civil engineering. This article focused on how to design, built and operate a structure health monitoring system for the noval steel-free cable stayed bridge, and a knowledge discovery model, SG（Simplified-General）modle was provided for analyzing the collected data.
