A Study on the Fatigue Characteristics to Improve the Eng Bond Properties of Strengthening Concrete Beam

단부 부착력 개선을 위한 보강콘크리트보의 피로특성에 관한 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 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 plate at the end.
