摘要
研究了适用于系杆拱桥拱肋结构的损伤识别方法,由于模态柔度对结构损伤的高灵敏性,采用模态柔度改变率作为指标,考虑各种损伤情况,运用该指标进行仿真分析,通过计算的数值表明,模态柔度改变率法可以准确有效地判断损伤位置,定性地判断同一位置处的损伤程度。
The method of damage identification for the tied arch bridge structure is studied in this paper, because of the modal flexibility on structure damage with high sensitivity, the modal flexibility change rate is used as an indicator when doing model simulation analysis considering a variety of damage. The analysis results prove that model flexibility change rate method can accurately judge the damage location, qualitatively determine the degree of damage of the same position.
