Research progress on the compressive mechanical behavior of cold-formed thin-walled steel columns

This paper summarizes the mechanical behavior of cold-formed thin-walled steel columns (CFTWS) under compressive loads. The research methods include experimental analysis, theoretical calculations, and numerical simulations. By introducing the research progress of CFTWS columns under compression, this paper aims to help readers quickly gain insights into the issues they are interested in. By analyzing decades of literature on the compressive research of CFTWS columns, future development trends are outlined. The analysis reveals that theoretical research, standardization, and prediction of buckling behavior for CFTWS are still inadequate. Additionally, more theoretical work is required to accurately predict the performance of CFTWS under complex loading conditions and extreme environments. This paper is capable of offering valuable references for the promotion and application of CFTWS structural technology.
