The energy dissipation performance of regular polygonal columns and diamond columns under quasi-static axial compression was investigated by INSTRON material testing machine. The effect of deformation mode and pressure equalization on the diagonal elements of the central angle is studied. The compressive ability of polygonal columns and corner elements under quasi-static and dynamic axial compression is studied by numerical analysis. The pressure and deformation mode of the polygonal column obtained by numerical calculation are in good agreement with the experimental results. In addition, based on the results observed in the experiment, the energy dissipation mechanism is discussed.
