Abstract

The deteriorated continuous rigid frame bridge is strengthened by external prestressing. Static loading tests were conducted before and after the bridge rehabilitation to verify the effectiveness of the rehabilitation process. The stiffness of the repaired bridge is improved, and the maximum deflection of the load test is reduced from 37.9 to 27.6 mm. A bridge health monitoring system is installed after the bridge is reinforced. To achieve an easy assessment of the bridge’s safety status by directly using transferred data, a real-time safety warning system is created based on a five-level safety standard. The threshold for each safety level will be determined by theoretical calculations and the outcomes of static loading tests. The highest risk threshold will be set at the ultimate limit state value. The remaining levels, namely middle risk, low risk, and very low risk, will be determined using reduction coefficients of 0.95, 0.9, and 0.8, respectively.
