CHARACTERISTIC, REVIEW AND PERSPECTIVE OF HYBRID STRUCTURE BRIDGES

Abstract

 The hybrid structure combining steel and concrete has been adopted on expressway bridges as a excellent in economy, seismic design and maintenance. These hybrid structures can be classified into composite structures such as corrugated steel web bridges and composite truss bridges, and mixed structures in which steel girder and RC pier or steel girder and concrete girder. This paper describes each case, development history and characteristic, review and perspectives. In particular, regarding the corrugated steel web structure, its buckling, jointing method and dynamics were described. For the composite truss structure, the characteristic of the truss joint and the review in construction are described. For the mixed structure, the jointing method of the composite rigid frame structure are described. For the mixed structure where the steel girder and the concrete girder are joined, the review and the characteristics of the jointing method are described. Finally, perspective for composite structures are described.
