Abstract：In order to further study the mechanical performance of recycled concrete-filled circular steel tube short columns under axial compression, the force process of recycled concrete-filled circular steel tube short columns, steel tube and recycled concrete were analyzed, and the change trend in the bearing capacity of steel tube and recycled concrete was studied. The influence of such factors as the replacement ratio, ratio of steel, recycled concrete strength and steel tube strength on the ultimate bearing capacity of recycled concrete-filled circular steel tube short columns under axial compression was discussed. The results show that the replacement ratio has little influence on the ultimate bearing capacity of recycled concrete filled steel tubular columns under axial compression. But the ultimate bearing capacity can be effectively affected and improved by the ratio of steel, recycled concrete strength and steel tube strength.
