Research on Safety Assessment Theories and Application of the Internal Force Envelope Method in the Health Monitoring of Large

Abstract:

This paper puts the internal force envelope method in bridge design into the safety assessment of bridges’ health monitoring, and proposes a safety assessment technology based on the method, which is stated in three aspects: the safety assessment modal, the acquirement of the real-time Figure of bridges’ internal force resistance and of the real-time Figure of bridges’ internal force. After the application in the Nu Jiang Bridge, it is proved that the safety assessment technology based on the internal force envelope method is simple, easy to understand, reliable, visualized and prospective in further application.
