Strengthening method of steel-concrete composite bridges using external tendons has been found to one of the most effective techniques of reinforcement and its application is increasing. In this paper, experimental test was carried out to prove the effects of increasing in yield loading and ultimate loading of steel-concrete composite beam strengthened by external tendons. Quantitative analysis is carried out to evaluate the effects of variables such as existence or nonexistence of tendon force, existence or nonexistence of deviator, tendon eccentricity and the shape of strands under the working load.
