Abstract


Steel - concrete composite beam structure is developed in the steel and reinforced concrete structures based on a new type of structure , side by side with a wooden structure , masonry structures , reinforced concrete structures and steel structures , has expanded to become the fifth largest structure ( a combination of structure ) , it is by connecting pieces of steel beams and concrete slab is connected into a whole work together flexural members . Under load , the concrete slab under pressure while the steel beams pulled , give full play to the material properties of steel and concrete , practice has shown that the advantages of both steel and concrete structures , with significant economic and social benefits , will be the structure one of the important direction of development of the system , a concrete composite beam as a composite structural systems , lateral load-bearing elements of steel buildings and bridges structure is bound to have broad application prospects . In this paper, steel concrete composite beams curved bridge engineering background , use of the finite element program sap2000 and ANSYS analysis of the mechanical characteristics of the connection key , the the connection key force analysis method to analyze the key in the form of different connections on curved steel - concrete composite girder bridge Force Influence ; analysis of concrete shrinkage and creep on the curve of steel - concrete composite girder bridge internal forces affect the concrete shrinkage creep analysis of composite beam internal force calculation . To elaborated curve calculation of composite beam prestressed analysis of prestressed composite beam internal force ; negative moment area of ??design control measures and calculation methods and negative bending cracks in analytical methods ; curve of steel-concrete combined with a real bridge dynamic performance of composite girder bridge . The results of this research available for similar bridge design reference .
