Outline of Final Research Achievements |
The long-term external load acting on steel-concrete joint connection in steel-concrete hybrid structural system may induce additional deformation in shear connectors and their surrounding concrete. The long-term slip increment in shear connecting system leading to the deformation of joint connection is experimentally and numerically clarified in this research. The push-out test specimens with headed stud shear connectors were loaded with sustained external shear force for a month, and the long-term slip was numerically simulated by nonlinear finite element analysis. Furthermore, the long-term sustained loading test of joint connection between composite girder and prestressed concrete girder was also conducted so that the long-term deflection increment under various load level was quantified.
