在铝合金混凝土筒（CFAAT）中增加了内碳钢管，进一步提高了该复合材料构件的承载能力。本文对CFAAT内碳钢短柱的轴压性能进行了试验研究。对6个CFAAT试件和4个相应的空心金属管进行轴压试验，试验参数包括内管尺寸和混凝土强度。实验结果表明，空心金属管的破坏是由向内和向外的局部屈曲引起的，而CFAAT试件只观察到向外的局部屈曲。额外的内碳钢管有助于提高CFAAT柱的强度和延性。随着筒内尺寸和混凝土强度的增加，复合构件的极限强度有增大的趋势，而混凝土强度越高，构件的延性越低。最后，分析了内碳钢管对CFAAT柱承载能力的贡献。
An additional inner carbon steel tube is employed in the concrete-filled aluminum alloy tube (CFAAT) to further enhance the load-carrying capacity of this composite member. The axial compressive behavior of CFAAT stub column with inner carbon steel tube is experimentally investigated in this paper. Six CFAAT specimens and four corresponding hollow metal tubes were tested under axial compression, and the test parameters included the dimensions of inner tube and the concrete strength. The experimental results showed that, the hollow metal tubes failed due to both inward and outward local buckling, while only outward local buckling was observed in the CFAAT specimens. The additional inner carbon steel tube contributed to the increase in both strength and ductility of the CFAAT columns. The ultimate strength tended to increase with increasing the inner-tube dimensions or the concrete strength, while a higher concrete strength led to a reduced ductility of the composite member. Finally, the contribution of inner carbon steel tube to the load-carrying capacity of CFAAT columns was analyzed.
