Research on Load Transverse Distribution Coefficient of Steel-concrete Composite Girder Bridge
Steel-concrete composite girder bridges are widely used in bridge construction,but the calculation method of load transverse distribution coefficient has not been stipulated in the domestic composite girder bridge code.In order to study the calculation method and influencing factors of the load transverse distribution coefficient of the steel-concrete composite girder bridge,the project takes the steel-concrete composite girder bridge as the object,and uses the software Midas/Civil to establish the spatial bar model of the steel-concrete composite girder bridge to calculate the load transverse dis-tribution coefficient.Compared with the traditional theoretical calculation results,the feasibility of the finite element method to calculate the transverse distribution coefficient is verified,and the finite ele-ment modeling method of the spatial bar system suitable for the engineering practice is obtained.On this basis,the parametric analysis of the model is carried out to determine the influence of the thickness of the bridge deck and the number of beams on the lateral load distribution of the steel-concrete composite girder bridge.The research results can be used to improve the specification of composite girder bridge and provide reference for the structural design of composite girder bridge in practical engineering.
