Through orthogonal test, the main influencing factors to the ultimate bearing capacity, ductility and energy consuming ability of L-shaped concrete-filled rectangular composite steel tubular columns are studied. Research results show as follows: the most important factor in deciding the ultimate bearing capacity is the steel tube wall thickness; the most important factor in deciding the ductility factor is the steel tube wall thickness; the most important factor in deciding the equivalent viscous damping coefficient is the strength classes of concrete. At the same time the best level combination of these factors are got.

By using finite element software ABAQUS, the nonlinear finite element analysis of earthquake resistance behavior of T-shaped concrete-filled rectangular composite steel tubular columns is carried out, furthermore, the analysis results and the corresponding experiment results are compared. The results indicate that the calculated value of ultimate bearing capacity is less than the experimental value, and the results of FEM analysis can match the experiment results better, and thus, it can better reflect the earthquake resistance behaviors of the specimens.

By using finite element software ABAQUS, the nonlinear finite element analysis of earthquake resistance behavior of L-shaped concrete-filled rectangular composite steel tubular columns is carried out, furthermore, the analysis results and the corresponding experimental results are compared. The results indicate that the finite element calculated value of ultimate bearing capacity is less than experimental value; axial compression ratio of the specimen has little affect on its ultimate bearing capacity and earthquake resistance behaviors; the results of FEM analysis can match the experiment results better, and thus, it can better reflect the earthquake resistance behaviors of the specimens.
