COMPOSITE GIRDER GIRDER BY PSC GIRDER AND STEEL GIRDER

摘要

PURPOSE: A composite girder of a steel girder and a PSC girder is provided to complement the weakness of a PSC girder, and to elastically support the extension length of a bridge. CONSTITUTION: A composite girder of a steel girder and a PSC girder comprises a PSC girder(100) and a steel girder(200). The PSC girder is manufactured in order to have a fixed extension length(L1). The fixed extension length is determined by the length of a pre-manufactured girder form. The steel girder is manufactured in order to have a variable extension length(L2).
