Abstract:
In order to promote the use of steel-concrete composite bridges in small and medium span bridges, and improve industrial construction of bridge and assembling degree of the composite girder bridge, an integrated prefabricated steel-concrete composite girder bridge was proposed. Considering the requirements of small and medium span bridges and the condition of highway transportation, the basic unit of the integrated prefabricated steel-concrete composite girder was constructed, and the connection way of units was put forward so as to further form the whole bridge. According to the result of calculation and analysis, the mechanical behaviour of the integrated prefabricated steel-concrete composite girder is superior to the traditional separated prefabricated steel-concrete composite girder, and it also performs better than the existing prefabricated concrete box girder and prefabricated concrete T-shaped girder in economy from the prospective of cycle. Besides, by comparing with the existing prefabricated concrete box girder, the prefabricated concrete T-shaped girder and the separated prefabricated steel-concrete composite girder, the integrated prefabricated steel-concrete composite girder would significantly improve the construction efficiency and shorten the construction period, and the construction quality could be guaranteed. All in all, the integrated prefabricated steel-concrete composite girder is a rational structure with convenient construction for bridge engineering.
