摘要/Abstract

摘要：

提出一种基于广义柔度矩阵的结构损伤识别方法. 以悬臂梁结构为例, 比较了柔度灵敏度方法和广义柔度灵敏度方法的损伤识别效果. 结果表明, 广义柔度灵敏度方法能更准确地识别损伤位置和程度.

关键词: 广义柔度矩阵；灵敏度；损伤识别

Abstract:

The authors presented a structural damage identification method based on generalized flexibility matrix. The generalized flexibility matrix is first introduced and then used to detect the structural damage. Finally, a numerical example of a cantilever beam is used to illustrate the effectiveness of the proposed method.

Key words: generalized flexibility matrix, sensitivity, damage identification
