Abstract
En 中文
• Developed a dynamic safety evaluation and forewarning method for bridge cable replacement. • Developed real-time methods for cable force and girder deflection identification during cable removal. • Developed MTGP method for data reconstructing and predicting to address the inevitable data missing issue. • Proposed three risk probability indices for structural safety evaluation during cable replacement. • Validated the proposed method using a real cable replacement project of a 24-year-old cable-stayed bridge.
