초록
Strengthening method of steel-concrete composite bridges using external tendons has been found as one of the most effective techniques of reinforcement and its application is increasing. In this paper, experimental test was carried out to show the effects on the yield loading and ultimate loading of steel-concrete composite beams strengthened with various configurations of external tendons. Quantitative analysis is carried out to evaluate the effects of experimental variables such as tendon force, deviator, tendon eccentricity and the shape of strands.
