Abstract

An analytical model of a double-skinned composite tubular (DSCT) column was developed and verified using test results. The experimental results demonstrated the rigour and the validity of the present analytical model. Brief parametric studies were carried out for DSCT columns. The developed model considered the confining effect and material non-linearity of concrete. By the buckling or yielding condition of the inner tube of a DSCT column, its failure mode and concrete model were defined. The strength of concrete, the hollow ratio of a DSCT column, and the thickness of an inner tube were selected as the main parameters that affect the behaviour of a DSCT column. The analysis results showed that concrete strength and the thickness of the inner tube affect the axial strength and moment capacity of the column, while the hollow ratio affects only its axial strength.
