Abstract：In order to study the mechanical properties of components under different concrete strength and specimen size, the experimental study for two axial compression components of GFRP-concrete-steel tubular composite column (DSTC) was carried out.On the basis of establishing the analysis model, the load-strain curves and the change trend of bearing capacity for 8 axial compression components were simulated and analyzed with the nonlinear finite element analysis software ANSYS.The results show that when the strength grade of concrete gets improved, the mechanical properties of DSTC were significantly enhanced.When the size of specimens is different, the size effect has a certain influence on the mechanical properties of DSTC with different strength grades.
