Damage and collapse mode of existing post tensioned precast concrete bridge: The case of Petrulla viaduct

摘要

This paper describes an investigation into the collapse mode of a single-span, segmental post-tensioned concrete bridge caused both by the effect of chloride induced corrosion in Prestressed Post Tensioned Bridge and by some initial faults during tendons design. Collapse was determined by the breakage of the tendons and the wires inside the tendons appear completely rusted.
