Abstract: Prestressed concrete structure has undergone several decades of digestion and absorption, and re-innovation since its introduction to China, which has become one of important structural forms to achieve further enhancement of structural performances and meet diverse design demands. Prestressed concrete structure has been widely applied and a large number of prestressed concrete buildings and structures have been constructed up to now.The key techniques and development status in the field of the performance evaluation on prestressed concrete structures from the aspects of development history, performance evaluation needs, prestress detection and monitoring techniques, and performance evaluation methods were expounded. The future development trends of prestressed concrete structure from the three aspects of theory, techniques and application were envisaged. The future development directions involving uncertainty evaluation theory, material-structure-integrated evaluation techniques, and intelligent service performance evaluation methods were focused. It was expected to provide references to research and practice in the field of prestressed concrete structure.
