- The increase use of the stainless steel in engineering, especially in some industrial architecture and ocean structure concrete filled double tubular column occurred which use stainless steel tube replaced the outer steel tube in CFDST. There has some research of CFDST on the static load, dynamic load, durability and construction loads, the study of CFDST with external stainless tube is still in its infancy. In this paper, using of “ABAQUS” establish finite element analysis model. In the analysis model, the all materials mechanic behavior and contact method have been defined. The comparison between the “ABAQUS” calculating results and the test results has showed their consistency. The proved model and orthogonal method, the parameter analysis has been carried out. To the stainless steel-concrete-steel tubular columns, the analysis parameters include nominal steel ratio, hollow ratio, concrete cube strength and the ratio of diameter of inner steel tube to thickness. Based on the parameter analysis, the calculating method for the ultimate bearing capacity of stainless - steel concrete which have been compared.
