“…Moreover, hybrid girder cable-stayed bridges offer excellent construction adaptability, enabling simultaneous construction of the cable towers and concrete box girders for the side spans. These bridges have gained widespread usage worldwide, featuring notable examples such as the Kurt Schumacher Bridge in Germany [ 7 ], the Normandy Bridge in France [ 8 ], the Russian Island Bridge in Russia [ 9 ], the Tatara Bridge in Japan [ 10 ], and the Yongjiang Bridge in China [ 5 ]. Table 1 presents the top ten main spans of hybrid girder cable-stayed bridges globally.…”

The axial force transfer ratio of steel–concrete joints in hybrid box girder bridges is crucial for bridge design. However, the current standard oversimplifies the transfer ratio distribution coefficients, and both model tests and finite element analysis are time- and labor-intensive. This article proposes a simplified calculation model based on the deformation coordination theory to estimate the transfer ratio of the axial force between the bearing plate and shear connectors of the steel–concrete joint under compression bending conditions. Additionally, a large-scale model (1/5 scale) is established, and the mechanical properties of the steel–concrete joint section under compression-bending conditions are experimentally tested. A three-dimensional finite element model is developed and verified using the obtained test data. Results confirm the favorable mechanical properties and ample safety reserve of the SCJ, with all components remaining within the elastic stage under 1.6 times design conditions. By comparing the axial force transfer ratios obtained from the simplified calculation model and the finite element model, a small difference is observed, validating the reliability of the simplified calculation model. This paper provides a straightforward and efficient method for the design and evaluation of steel–concrete joints in hybrid box girder bridges.
