Discussion on Durability Design of Concrete Bridge Structures

Concrete structures will be deteriorated and damaged because of the natural environment and the long-term usage.The deterioration of the structural behavior and the damage inside the structure always affect the safety and suitability of a bridge structure.Therefore,the durability of structure is one of the important objectives for the reliability of engineering structures.In design calculations,besides considering bearing capacity,flexibility control and crack control,durability design must be considered.
