Analysis of mechanical characteristics of shear connectors in steel-concrete composite section of hybrid girder cable-stayed bridge
The steel-concrete composite section of a long-span hybrid girder cable-stayed bridge is taken as the research background.The steel-concrete composite section model is established by ABAQUS finite element software,and the mechanical characteristics of shear connectors in steel-concrete composite section under the most unfavorable axial force load condition and the most unfavorable bending moment condition are analyzed.The results show that under the most unfavorable axial force load condition and the most unfavorable bending moment load condition,the bearing capacity of the shear connector of the steel-concrete composite section meets the design requirements,and the PBL shear connector at the web and stiffener can effectively suppress the relative slip between the steel-concrete interface.
