A study on structural health monitoring scheme of cables and ties of caiyuanba bridge

摘要

In order to obtain structural health monitoring scheme,a finite element analysis model of caiyuanba bridge is established in this paper to analyze that how severe to the structure would be resulted by the damage of tied-bars,arch cables and the support cables of Y shaped beam.It is difficult to select type and position of sensor for cables since there are many cables in the bridge and its force is very great.So the sensitivity analysis of tied-bars,arch cables and the support cables is performed and the sensors are selected to detect damage of the bridge.Considering economy and safety of the bridge,a structural health monitoring scheme of the tied-bars,arch cables and the support cables is put forward based on the analysis results in the paper.
