| 摘 要： | 提出一种应用振动模态频率变化值和静力位移变化值之比而建立的综合识别指标对桥梁损伤进行分析与评定.试验结果表明,应用该方法能够对损伤的位置和程度进行准确的定位和评估.既安全又方便,可为现在的桥梁检测提供参考. |
| 关 键 词： | 综合识别指标 损伤定位 损伤程度 |

| Authors: | AO Ran others |
| Abstract: | The paper puts forward that analyzing and assessing the damage of bridge by integrated identification indexes established by ratio between changing value of vibrational mode frequency and one of static displacement.Tested results make known applying present method could accurately position and assess the damage and its extent,and is safe both and convenient. |
| Keywords: | Integrated identification indexes Position of damage Extent of damage |
