A Data-Driven Health Assessment Method for Cable-Ctayed Bridges
In order to monitor the safety performance of the bridge structure during operation,this study proposed a method combining data-driven and finite element model to assess the health of the cable-stayed bridge The method used the cable group force as a medium,used modifying the finite element model with the measured data,and enriching the negative sample of the bridge group cable force the Monte Carlo simulation method.Finally,the real-time status of the cable-stayed bridge through the difference measurement was evaluated.The method was discussed based on a domestic concrete single-tower cable-stayed bridge as the engineering background in this article.The results showed that the method takes into account the coordinated response of each component within the overall structure in the finite element model and the real change law of the structure in the monitoring data.It can quickly and quantitatively evaluate the health status of cable-stayed bridges,providing a basis for bridge maintenance decision-making.
