Abstract:
In order to safeguard the safety of bridges, capabilities to locate and quantify damage of strain indexes(including bending strain and shear strain)were considered as basic characteristics of the method to be investigated. The application processes of this kind of indexes were proposed and the effectivenesses were demonstrated by several numerical simulation examples. The optimization manner of measurement point was also proposed to meet the requirement of actual application. Furthermore, the existence, uniqueness and stability of the detection results were analyzed and then suggestions for improvement were provided. Results show that the method based on strain index is sensitive to tiny damage and allows simple, convenient detection for bridge damages.
