It was found in recent research that short SMA columns resist buckling better than nearly all other engineering materials. In this study, SMA was integrated into a column of aluminum to improve the post-buckling characteristics. The load of the original aluminum column drops drastically after buckling so that the absorbed energy is low. After a portion of the aluminum column is replaced with SMA, the load drops only a small amount after buckling and then increases again as end-displacement increases further. The experimental results show that the absorbed energy of the hybrid column is 1.9 times larger than that of the Al column. Simulation was also performed on the buckling process of the columns and the simulation results show similar trend to the experiment in variation of post-buckling load.
