The structural measures about puting the additional energy dissipation plat at the bottom of the CFST columns where bears more stress, was proposed to improve the seismic energy dissipation performance of concrete filled circular steel tubular (CFST) columns. Selecting the axial compression ratio and height of the energy dissipation plate as parameters, finite element anylsis of 8 circular CFST columns with different structural measure were performed. On the basis of finite element anylasis results, this paper, which obtained load-displacement curves of each finite element model, analyzed and compared the bearing capacity of each model. The results show that: comparing to the ordinary circular CFST columns, the columns with energy dissipation plat show much better performence about bearing capacity and seismic capacity, the height of the energy dissipation has a great effect on bearing capacity but the bearing capacity is inversely proportional to the axial compression ratio.
