The design of steel column base plays a very important role in steel structure design. Through large-scale analysis software ANSYS, this paper analyzes the steel column base by finite element numerical simulation nonlinear analysis,and discuss the fracture behavior and restoring force characteristics of steel pipe column in different thickness and axial compression ratio,and the link between the two. The results showed that, (1) the section of most likely break focus on the bottom of vertical load plane in the middle of the steel column base. (2) with the increase of thickness, anti-cracking ability increased gradually.(3) Axial compression ratio of the specimen has little effect for anti-cracking ability relatively. (4) With the increase of anti-cracking ability, the seismic behavior of specimens gets heightened.
