| 摘 要： | 提出了结构损伤识别的柔度曲率法，该方法不需要原结构的模态参数，只需利用损伤结构柔度的曲率就可以识别结构的损伤位置。数值例子表明，柔度曲率法仅需要低阶模态信息即可获得很好的识别精度。

| Abstract: | A methodology to localize the damage in structures is presented in which only postdamage flexibility curvature is used. The damage location in structures can be identified without baseline modal parameters. The simulated cantilever beam and simply supported beam examples show that damage in structures can be detected with satisfactory precision by using only a few of the lower frequency modes. |
