This paper deals with the static compression behaviour of concrete-filled double-skin tubular (CFDST) columns with corrugated plates. These sections take advantage of the high strength of their infill concrete as well as the ductility of their steel skins. Static compression tests were performed on CFDST column specimens with inner or outer skins built up from corrugated plates. The steel hollow sections fabricated from corrugated plates exhibited a more stable response under axial compression loading. Hence, implementing them in CFDST columns is expected to enhance the overall behaviour of these columns. These tests reveal how the overall behaviour of CFDST columns is affected by replacing their inner/outer skin with one fabricated from corrugated plates. The corrugated plates have an insignificant effect on the strength of column specimens. However, the ductility and energy absorption capacity of CFDST columns are improved dramatically. A finite element modelling framework was also developed to simulate the response of CFDST columns with corrugated plates and validated against the results of the experiments.
