Abstract

Abstract

Deficient circular and square concrete-filled steel tube (CFST) columns can be reinforced with outer steel tubes effectively. In this paper, ABAQUS was utilized to establish finite element models for the circular and square CFST columns reinforced with outer steel tubes, respectively, and the models were validated through tests. Furthermore, the effects of the column end length, the thickness and strength of sandwich materials, the ratio of diameter and thickness and the yield strength of steel tubes, and the core concrete strength on the axial compression performance of the CFST columns reinforced with outer steel tubes were analyzed. The results show that no extra strengthening configuration is needed for the column with the diameter greater than 300 mm if the column end length is less than 60 mm. The low thickness and high strength of the sandwich materials can guarantee the reinforcement effect of the outer steel tubes. In addition, a small ratio of the diameter and thickness of the outer steel tubes, large ratio of the diameter and thickness of inner steel tubes, and low core concrete strength can improve the reinforcement effect of the outer steel tubes. According to the superposition method, methods for calculating the axial compression bearing capacity of the circular and square CFST columns reinforced with the outer steel tubes were proposed, and the prediction results are in good agreement with the test and finite element results.
