Effects of corrosion of the unbonded tendons on the mechanical behavior of the tendons and bearing capability of the structure are discussed.

The embedment of unbonded tendons,the calculation of elongation value,the key points in construction of swimming anchor angle tension and so on are introduced,providing a reference for relevant construction.

Characteristics and applications of equivalent loads in unbonded prestressed tendons;

The flexural behavior of partially prestressed concrete beams with unbonded prestressing CFRP tendons and epoxy coated steel bars is investigated,and the full-range tests are loaded for 8 beams until the failure.

The construction technology of un-adhered prestressed concrete of the middle sediment pond at the Herdongs sewege plant;

Research on law of stress increment of unbonded tendons in continuous prestressed concrete beam and slab;
