Assessing the response and fragility of concrete bridges under multi-hazard effect of vessel impact and corrosion

Bridges crossing navigable waterways have a high risk for vessel collision hazard, and are meanwhile experiencing significant ‘aging’ hazard due to the surrounding aggressive environments. These bridges must be designed to be resilient to both episodic (vessel collision) and chronic (structural deterioration) hazards. To achieve this goal, this paper will develop a novel fragility assessment framework for reinforced concrete (RC) bridges under …
