Abstract
AbstractIn order to evaluate the health status of Steel-concrete composite girder bridges, a health status assessment model based on the bridge monitoring scheme is proposed, and a matching data analysis method is established on this basis. Firstly, the data are divided into two index layers: monitoring projects and monitoring points, and a health status assessment model is established based on this. Secondly, the fuzzy comprehensive evaluation of the state of Steel-concrete composite girder bridges is realized by the membership vectorization processing of the monitoring data. Finally, the method is applied to an actual bridge to evaluate the health status. The results show that the established model and method can evaluate the state of the Steel-concrete composite girder bridge, and the state of the bridge evaluated by this method is level 1 and the health is better. The health status assessment model and data analysis method of Steel-concrete composite girder bridges establishes a direct connection between objective data and subjective assessment, provides an effective way for the real-time evaluation of bridge health status.
