Abstract EN
Performance evaluation of a bridge is critical for determining the optimal maintenance strategy.
An unsupervised bridge superstructure state assessment method is proposed in this paper based on fuzzy clustering and bridge field measured data.
Firstly, the evaluation index system of bridge is constructed.
Secondly, a certain number of bridge health monitoring data are selected as clustering samples to obtain the fuzzy similarity matrix and fuzzy equivalent matrix.
Finally, different thresholds are selected to form dynamic clustering maps and determine the best classification based on statistic analysis.
The clustering result is regarded as a sample base, and the bridge state can be evaluated by calculating the fuzzy nearness between the unknown bridge state data and the sample base.
Nanping Bridge in Jilin Province is selected as the engineering project to verify the effectiveness of the proposed method.
