Abstract: This paper provides test data on the buckling behaviour of cone with uneven axial height subjected to axial compression. The cone axial height has sinusoidal waves along the circumference of small radius end. First, numerical analysis was carried out for a range of axial imperfection-to-axial height ratio. Next, laboratory-scaled experiment was conducted on a selected axial imperfection-to-axial height ratio, to confirm the appropriateness of the numerical approach employed in the paper. Results reveal that the buckling load of the cone is strongly dependent on the number of waves of axial imperfection and the axial imperfection amplitude. In addition, comparison between experimental and numerical results shows a good agreement with ratio of experimental to numerical buckling strength ranging from −5 to +6.

Keywords: buckling; mild steel cone; axial compression; ABAQUS simulation; uneven length.
