Abstract     [Full Text]
    Concrete filled steel tubular (CFST) member has been widely used in the construction of highrise buildings for its high axial bearing capacity. It can also be applied on long-span structures such as spatial structures or bridges not only for its high bearing capacity but also for its construction convenience. Concrete casting effect of CFST member is considered in the study of its bearing capacity in this paper. Firstly, in order to authenticate the applicability of constitutive relationship and yield criterion of steel and concrete based on FEM, two ANSYS models are built to simulate and compared with other
 
Key Words
    CFST; bearing capacity; the nonlinear finite element method; concrete horizontal casting effect.
