Abstract: In order to study the mechanical properties of aluminum alloy and stainless steel new type of metal tubes andtheir concrete short columns, axial compression tests were carried out on specimens of four short columns with differentmaterials, and the failure process and stress characteristics of the new type of metal tubes and their concrete short columnswere summarized and analyzed. The test results show that the new type of metal tubes has higher bearing capacity and goodductility, and the stainless steel tube concrete short column has higher bearing capacity and better plastic properties. Thefinite element software ABAQUS was used to perform finite element simulation analysis on the new type of metal tubeconcrete short column. The finite element simulation analysis was in good agreement with the test specimen bearing capacityand ductility curve results, which verified the accuracy of the finite element simulation analysis.

Keywords:aluminum alloy; stainless steel; new type of metal tube; concrete short column; axial compression test; finiteelement simulation analysis
