摘要:
曲率模态是结构损伤识别的敏感标示量,采用数值仿真方法,把曲率模态用于桥梁损伤识别,在位移模态中引入噪声之前,曲率模态检测方法能准确判断出损伤的位置,此时,检测结果有很高的准确度和精度,可以检测出结构中出现的损伤.引入噪声后,当位移模态噪声小于1%时,噪声的影响不太明显,仍可以把损伤位置检测出来,但当位移模态噪声大于1%后,不能把损伤位置检测出来.
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.
