The earthquake resistant experimental research on knee joint of concrete structures with short flanged wall and unbonded prestressed slab;

Research on prestressing losses of prestress without bond beam;

This paper presents the construction technology and technical keys of circumferretial prestress without bond for Zhangyang U-shape thin-shell flume.

This paper introduces the application of the prestress without bond technology in the utltra long structure of Shanxi Museum, which includes binding and tension of the prestressed reinforcement.

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.

Nonlinear analysis of the unbonded prestressed reinforced concrete beam;

Technical and economic iimpact factor analysis on unbonded prestressed concrete flat slab floor

The bonded prestressed concrete structural wide flat beams were employed as the frame beams, while the unbonded prestressed concrete structure was applied to the junior beams.
