Abstract

This paper takes thin-walled square CFST columns with lining tube as the research object, aiming to conduct finite element analysis and parameter comparison on their axial compression performance. This member is a new type of composite column, with internal steel lining tubes and outer steel tubes connected by slot welds, which has the advantages of simplified manufacturing process and good constraint performance. To further investigate the mechanical performance of this member, Abaqus was used to conduct axial compression finite element numerical simulation on 18 short columns in this paper. Through parameter analysis, the influence of inner lining to outer pipe, inner pipe strength, external steel pipe strength, and concrete strength on the mechanical properties of components is discussed. The results show that the lining significantly increases the load carrying capacity of thin walled CFST columns, and also significantly improves the ductility of the parts. Meanwhile, as the strength of the internal and external steel pipes and the load carrying capacity of the parts increases, the strength of the concrete also significantly affects the mechanical properties of the components.
