摘要: 为研究铝合金、不锈钢新型金属管及其混凝土短柱的力学性能,对 4 种材料不同的短柱试件进行轴压试验,总结并分析了新型金属管及其混凝土短柱的破坏过程和受力特征. 试验结果表明,新型金属管具有较高的承载力和良好的延性,而且不锈钢管混凝土短柱有较高的承载力以及较好的塑性性能. 利用有限元软件 ABAQUS 对新型金属管混凝土短柱进行有限元模拟分析,有限元模拟分析与试验得到的试件承载力、延性曲线结果吻合较好,验证了有限元模拟分析的准确性.

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
