Influences of Difference Construction Methods of Steel and Concrete Composite Camber Beam Bridge on Internal Force of Structure
With the development of economic and transportation construction,the composite camber beam bridge has gradually become the preferred bridge type in urban bridge construction.The internal force of composite camber beam bridge is different from that of straight bridge.The different construction method will involve the different system prefabricated combined curved girder bridges are different from those of straight bridges,and the different construction methods involve the different system conversion problems.Therefore,the choice of construction methods will have an impact on the mechanical properties of the structure.Based on the three construction methods of the composite camber beam bridge-first simply supported then continuously supported,first fulcrum then mid-span and full framing construction,the construction process of different construction methods is simulated by finite element software to study the influence of different construction methods on the structural mechanical properties of the composite camber beam bridge.Aiming at the prefabricated composite camber beam bridge,the reasonable construction methods of main girder and cross girder are proposed,which had the guiding significance in the selection of the reasonable construction method of the main girder for the composite camber beam bridge from the viewpoint of structural stresses.
