| 中文摘要: |
贾有权先生早年留学美国。新中国的成立，使他受到极大的鼓舞。他毅然决定放弃美国政府及所在大学提供的学习机会与待遇，于1950年春，就怀着一片赤子之心与华罗庚等留美青年学生同船回到了祖国，任教于北洋大学，立即全身心地投入到力学的教育和研究中。

| 英文摘要: |
| The debonding detecting of FRP-concrete interface is a difficult problem in interface mechanics analysis. Infrared detection technology was used to record interfacial fatigue behaviors and analyze the interface fatigue damage processes. Based on three standard specimens, the probe accuracy, feasibility and interface debonding criterion of infrared detection measure were studied. Results show that initial debonding areas exist in the interface of RC beams strengthened with FRP. At an early stage during cyclic loading, the interfacial debonding expands rapidly then maintains stable in most fatigue life; the instability occurred during the last thousands cyclic loading results in a complete failure of strengthening RC beams. The fatigue loading number and the debonding area at every stages are presented in this paper based on infrared data. |
