| Abstract: | In this paper,ABAOUS finite element program is used for non-linear finite element analysis of short lightweight concrete-filled square cold-formed thin-walled steel tubular columns to compute and analyze the complete loaddisplacement curve of short lightweight concrete-filled square cold-formed thin-walled steel tubular columns under axial compression.The results show that stiffening ribs can improve carrying capacity of short lightweight concrete-filled square cold-formed thin-walled steel tubular columns.Meanwhile,this paper studies effects of the set-up way of stiffening ribs,steel strength,concrete strength and thickness of steel tubes on load-carrying properties of short lightweight concrete- filled square cold-formed thin-walled steel tubular columns. |
