Dynamic Performance Improvement and Fatigue Mitigation of Strengthened Box Girder Bridges With External Posttensioned Tendons: Modeling and Strategies

ABSTRACT This study evaluates the dynamic and fatigue performance of high‐speed railway (HSR) box girder bridges strengthened with external posttensioned tendons, using validated three‐dimensional finite element models and a fracture energy‐based fatigue model that integrates ext...
