Resistance Deterioration Assessment of Concrete Beam Bridges based on Strain Monitoring Data

The bridge health monitoring system deployed in concrete beam bridge mostly uses strain sensors to collect data and evaluate the working state of bridges. However, the existing evaluation method of bridge working condition based on strain data cannot realize the evaluation of whole bridge bearing capacity. To solve this problem, this paper puts forwards a resistance deterioration assessment method based on strain monitoring data and calculated maximum crack height. Through the engineering project verification, this method has been deemed to be effective.
