摘要：
Carbon fiber reinforced epoxy composite-aluminium alloy (CFRP-Al) stub column has the characteristics of lightweight, high strength and good ductility, showing a promising application prospect in long-span space structures. However, the research on its mechanical properties is basically in a blank state at home and abroad. For this reason, the theoretical analysis, experimental and numerical researches on CFRP-Al stub column were carried out in this paper. The equivalent elastic constants of CFRP-Al stub column were derived. The axial compression tests of six stub columns were completed and the axial bearing capacity and the failure mode of the short columns were obtained. The load-displacement curves calculated by the theory of elasticity show a good agreement with the test curves. Two numerical models, the layer-by-layer refinement model and the overall equivalent simplified model, were established using ABAQUS. The results of the two numerical models were compared with the experimental results. The comparison shows that both numerical models can well simulate the axial compression performance of CFRP-Al stub columns. Copyright ©2021 Acta Materiae Compositae Sinica. All rights reserved.
