A Study on the Fatigue to Improve the End Bond Properties of Repair and Strengthening Member

보수 보강 부재의 단부 부착력 개선을 위한 피로실험 연구

The concrete structure under fatigue load depresses in mechanical capability or breaks down finally because of the fatigue. So recently the study on strengthening methods using bonded steel plate is widely attended. Which could be constructed under use and without damaging the structure. The intention of this method is to increase the useability of the structure and to recover the strength. So application on fields are sharply increasing. In this study it is tried to develop strengthening methods using notches and anchor bolts which could supply the defect on falling off of the steel plate at the end.
