ABSTRACT = {This paper concentrates on the compressive strength of steel tube in
Concrete-filled steel tube (CFST) column. Through an elasto-plastic limit analysis
based on Twin Shear Unified Strength Theory (TSUST), the vertical load capacity
of the steel tube alone was analyzed by adopting a parameter <i>b</i>, which varies from 0
to 1. And the strength reduction factor has been derived by total theory of plasticity.
A new analytical formula, capable of predicting the axial bearing capacity of the
CFST stub columns subjected to axial compression, has been developed based on
the linear approximation of Mises yield criterion among TSUST. And There are
good agreement between the experimental and analytical results.},
