摘要： A joint structure for a mixed structure bridge is provided to prevent the stress concentration on a joint, to prevent the strength reduction by discontinuous planes and to prevent the lowering of constructability by a complicated inner structure of a joint. A joint structure(100) formed on a joint of a mixed structure bridge by a steel girder(10) and a concrete girder(20) comprises a main body portion(110) whose one side is coupled to the steel girder, and a projecting support portion(120) projected to the other side of the main body portion and coupled to the concrete girder to support a portion of the concrete girder upward. When the main body portion and the projecting support portion are formed in the L-shaped cross section, a steel plate forming the outside comprises an upper plate forming the upper part of the main body portion, a rear plate formed on the rear of the main body portion to face coupling planes of the steel girder, an upper front plate extended downward from the upper plate to face the upper rear plane of the coupling planes of the concrete girder, a middle plate extended forward from the upper front plate to face with the middle plane of the coupling planes of the concrete girder, a lower front plate extended downward from the middle plate to face the lower rear plane of the coupling planes of the concrete girder, and a lower plate coupled to the bottom of the rear plate and the bottom of the lower front plate.
