Abstract

The finite element(FE) software is used to simulate concrete-filled steel tubular(CFST) columns. Based on the existing experimental data, the model is verified. The parameters studied include axial load ratio and shear span ratio, and the difference of seismic performance between circular CFST column and square CFST column under the condition of equal steel ratio is compared. The results show that with the decrease of axial load ratio, the hysteretic curve is plumper and the seismic performance is more stable. With the decrease of shear span ratio, the horizontal bearing capacity of the specimen increased significantly, but the cumulative damage effect was more significant. The simulation results also show that when the steel ratio is identical for circular and square CFST columns, the circular CFST column has superior seismic performance.
