摘要
Aiming at the steel-concrete composite joint of railway long-span hybrid girder cable-stayed bridge, the development trend, research status and achievement as well as the existing problems of joints are expounded from the aspects of the development history, structure form, structural parameters and force characteristics, shear connector stress state, force transmission mechanism, fatigue performance and so on. The shear-compression composite joint with the steel roof and the floor plate inserted into the concrete section become the main form for the engineering practice. Its development trend is to shorten the length, simplify the structure, further optimize the overall structure, and make the layout more flexible. The length of composite joints between 1.5 m and 3.0 m has no significant effect on the stress and force transmission laws of the main girder. The reasonable thickness of the bearing plate is 40 mm to 70 mm, and the reasonable spacing of the shear studs is about 150 mm. Adding stiffeners (PBL plate) on the concrete side of the bearing plate, combined use of the shear studs and the PBL shear connectors as well as using the trapezoid and other new PBL shear connectors are the structure development tendency for steel-concrete composite joints. So far, model test and simulation analysis are the main means of stress analysis for the steel-concrete composite joint. The focuses of the further research are as follow: the calculation theory and simplified calculation formula of the overall bearing capacity, the inhomogeneity and distribution laws in the longitudinal and transverse directions of the shear stud stress, the shear-resistant theory and calculation analysis method for the combined use of the shear studs and PBL shear connector, the force transferring ratio of steel and concrete components and other shear-resistant and force transferring theories, the influence of the fatigue failure mechanism, and detail characteristics and structural parameters on the fatigue properties of steel, steel-concrete interface, shear connectors and concrete are all the research focuses. © 2022, Editorial Department of China Railway Science.
