ABSTRACT

Gangue concrete filled steel tube is a new composite system which has advantages of remarkable earthquake-resistant property and economical efficiency. However, few researches have been done with respect to the behavior of the composite system. Therefore, based on proper material constitutive models and reasonable contact models among different materials, the paper has developed finite element analysis models of rebar-penetrated connection between gangue concrete filled steel tubular column and reinforced gangue concrete beam using software ABAQUS 6.10. Furthermore, finite element analysis results are verified by experiments, demonstrating that the load-displacement curves computed by ABAQUS agree with experimental curves very well and finite element analysis models are reliable to analyze the behavior of the rebar-penetrated connection. Then, these models are used to conduct stress analysis on the composite connection to investigate the failure modes and the force-transferring mechanism. The analysis results show that the rebar-penetrated connection, with full and spindle-shaped load-displacement hysteretic curve, has the reasonable force-transferring route and good energy-dissipation capacity. Finally, the effects of axial load level, stiffness ratio of beam and column, steel ratio and compressive strength of gangue concrete on the behavior of the connection are investigated on the basis of the different models by changing the parameters.
