Abstract

Concrete continuous box-girder bridges, boasting excellent mechanical performance and construction convenience, have seen prevalent applications in bridge engineering. However, during long-term operation, these bridges are susceptible to various external environmental factors, leading to issues such as prestress loss, creep and shrinkage, and cracking, which subsequently affect structural safety. In light of this, for the sake of scientific assessment of the health status of bridges, this paper proposes a condition evaluation method for concrete box-girder bridges based on health monitoring data. The method opted for four types of evaluation indicators as the first level: cumulative test results, deformation and stress verification, trend analysis of monitoring data, and periodic inspection data. By applying the Analytic Hierarchy Process (AHP) to a continuous rigid frame bridge on a certain highway to calculate the weight of each indicator, this method enables a comprehensive evaluation of the bridge’s condition, providing effective decision support for bridge operation, maintenance, and reinforcement.
