| 摘 要： | 钢材在低温下脆性增大容易发生脆性裂缝 ,本文利用截面抗弯刚度的降低来模拟这种裂缝损伤 ,提出了用应变模态方法来识别这种损伤。回顾了近 2 0年来损伤识别的方法 ,详细阐述了应变模态方法的理论基础 ,最后对应变模态法的工程实用性进行了评价

| Abstract: | At low temperature, structural steel tends to be more brittle and cracks easily. In this paper, the crack is modeled by the degradation of flexural rigidity and the cracks can be detected with strain mode. Strain model analysis is a damage diagnosis method which is sensitive to damage location and damage degree. In the end,the application of strain mode method is evaluated. |
