This paper presents a review for the behaviour of spliced reinforced concrete girders that subject to static or cyclic loading. The splice technique was provided a solution for many problems of constructions and cost of bridge girders, such as casting, transformation, and installation. The researches were shown that the splicing implemented by either posttension system or without prestressing force. The posttensioned girders may be connected with cold joint or with cast in place (CIP) joint. All the girders splicing without prestress system made with CIP joint. These joints must be having length enough to accommodate the development length of reinforcement. Some of examples on the splice girder bridge was presented in this paper. As concluded, the joint region referred to weakness point in the girder and thus, must be generate some of a way to increase the continuity of girder at joint. The parameters that studied were (presence of shear key, increasing area and force of prestress strands, shape and type of joint, concrete type, and many technical to strength joint by FRP product). It was determinate that, the research in this topic need to many applications and technique to reach or near from monolithic girders with suitable cost and easy construction.
