One of the important issues on the work of steel-reinforced concrete bridges – taking into account the impact of the shift between concrete and steel structural elements. The reliability and durability of the structure depend on improving the accuracy of the calculation by modeling the actual operation of the structure of any complexity. However, it is necessary to develop a science-based methodology for the calculation of models of steel-concrete superstructures and structures combining concrete and steel.

In the analysis of experimental and theoretical studies of the calculation of steel-reinforced concrete bridges, there are significant differences in the stiffness values obtained by different authors for the binding elements of steel and reinforced concrete parts of the cross section of the structure. The requirements for the technology of calculation of steel-concrete span structures of bridges, including taking into account the ultimate shear stiffness of the joints of the steel beam with reinforced concrete slab, are not regulated in the developed interstate standards, and their early development as part of national standards is certainly one of the most important tasks in the implementation of TR CU 014/2011.

The proposed algorithm of calculation with the ability to take into account the flexibility of the shear connection allows you to Refine the calculation of steel-concrete span structures of bridges in accordance with modern computing power, allows you to increase the level of reliability of bridge structures, laid at the design stage.

Keywords: connecting elements of reinforced concrete and steel part of the superstructure; rigid, flexible, continuous support; anchor
