A structure for reinforcing a yield strength of a composite beam. The structure for reinforcing a yield strength of a composite beam comprises: a steel plate beam whose upper surface is opened along a longitudinal direction; and a pair of tendons whose one ends are mounted on upper portions of both ends of the steel plate beam and whose the other ends are symmetrically mounted on lower portions of a middle portion of the steel plate beam to transfer a weight of the middle portion to both ends of the steel plate beam to reduce sagging of the steel plate beam in the longitudinal direction. Accordingly, tension steel wires which can support the middle portion of the steel plate beam are provided to reduce sagging of the middle portion of the steel plate beam. Also, weights of the tension steel wires are distributed and accommodated to prevent local buckling of an interior of the steel plate beam. Also, the structure for reducing sagging of the interior of the steel plate beam is provided to elastically extend a length of the steel plate beam to increase universal use of the steel plate beam. |
