摘要：
This paper presents a comprehensive experimental and numerical study on the load-carrying behaviour of innovative high performance materials steel-concrete composite columns: Namely concrete-filled steel tube columns with solid steel core (CFSTCSC) and concrete-filled double steel tube columns (CFDST). The experimental results exemplify the basic load-carrying behaviour. In addition to that, the application range of high-strength materials is evaluated in relation to the slenderness. Finally, the influence of geometric imperfections on the load-carrying behavior is investigated based on the manufacturing tolerances of such multi-component cross-sections. © 2023 Ernst & Sohn GmbH.
