Abstract

This study examines the behaviour and strength of concrete-filled double-skin corrugated steel tube (CFDSCST) short columns when subjected to axial compression. Finite element (FE) models were created and verified for CFDSCST short columns utilizing existing experimental tests. Next, a study is conducted on the behaviour and axial strength of these columns, taking into account several elements that have an impact, such as the ratio of depth to thickness, the compressive strength of the concrete cylinders, the hollow ratio, and the strength of the steel. The findings demonstrate that increasing the tube thickness and the compressive strength of the concrete improves the strength of the column, while a higher hollow ratio decreases the capacity. These findings provide useful knowledge on the design and optimization of CFDSCST short columns for structural applications.
