摘要:简支梁与悬臂梁的多个算例表明:结构损伤识别的柔度差值曲率法仅需低阶的模态参数即可获得很好的损伤识别精度,对于轻微损伤与多处同时损伤的识别也是灵敏可靠的.

关键词: 结构, 损伤识别, 柔度, 柔度差值曲率, 模态参数

Abstract: The flexibility differential curvature method for structural damage identification is presented.By many examples of simply supported beam and cantilever beam it is showed that:good accuracy of damage identification will be obtained with lower order modal parameter,and minor damage and simultaneous multidamage identification is sensitive and reliable.

Key words: structure, damage identification, flexibility differential curvature, modal parameter
