The experimental work was performed to investigate the effect influenced to the hystresis and the flexural strength improvement of RC beam using carbon fiber plates. Major parameters of this experimental program were the section size of carbon fiber plates and the damage level of RC beam before reinforcement. Particularly, the damage level of beam is for the cases damaged by overloads. The damage level is for 30%, 60%, and 100% of flexural strength, and no damaged beams were also tested for comparison with the damaged one. from the test results, it showed that the beams reinforced by carbon fiber plates had the higher strength and lower deformation capacity than the general beams and that it had the same ductility ratio of the general beams.

In this thesis, the safety inspection of the T-beam bridges were studied. The stage of the safety inspection were classified according to the importance of the inspection contents the preliminary inspection, the resume inspection, the detail inspection, and the close inspection. By stages, the Inspection contents, the inspection items, and the inspection methods were systematized. And the method of the repair or the reinforcement for the demaged bridges were also suggested.
