应变模态法在结构损伤监测诊断的研究

Research on Strain Modal Method in Structure Damage Supervision Diagnostics

结构的应变模态对于结构损伤具有很高的敏感性,对于及时监测诊断结构的损伤保证结构的可靠性、安全性具有重要意义。本文从理论上研究应变模态的原理和应变模态参数识别方法。

Strain modal of structure is an important meaning to the reliability modal and the method of strain modal very sensitive to its damage. Supervision diagnostics on structure damage has and safety of structure. This paper theoretically studied the principle of strain parameter recognition.
