| Abstract: | The main bridge of JingYue Yangtze river bridge is a asymmetric hybrid girder cable-stayed bridge with a main span 816 m.The steel-concrete composite segment of the girder is composed of the steel box room packing concrete structure with part connected.In this paper,joint form of the steel-concrete composite segment is analysed and compared.It was analyzed and researched the proper detailed structure of steel-concrete composite segment（for example,the bearing plate,the shear connector,shear connector and prestress distribution）.Finally,through the force calculation and analysis,verify the safety of the precast hybrid girder. |
