- Abstract:
-
Curvature mode is the sensitive labeling quantity of structural damage recognition, using numerical simulation method, the curvature mode is used for bridge damage recognition, before the introduction of noise in the displacement mode, the curvature mode detection method can accurately determine the location of the damage, at this time, the detection results have high accuracy and precision, can detect the damage in the structure. After the noise is introduced, when the displacement mode noise is less than 1%, the influence of noise is not obvious, and the damage position can still be detected, but when the displacement mode noise is greater than 1%, the damage position cannot be detected.
