Abstract

The compressive behaviour of Concrete-Filled Double-Skin tubular (CFDST) sections consisting of corrugated plates is investigated numerically in this study. Finite element simulations are employed to decipher more details on the compressive behaviour of numerous archetypes with different geometries and material properties. The results of these simulations reveal how the ultimate static compressive capacity of the intended sections may be affected by changing the geometric and material properties. Different cross-section shapes, dimensions and heights within the practical range are considered for the proposed archetypes. In addition, a wide range of concrete compressive strength values are assigned to the concrete infill of the archetypes. The ultimate axial capacity of almost all the intended CFDST archetypes is mainly dominated by concrete compressive strength. In conjunction with numerical simulations, different design formulations are also employed to predict the ultimate axial load-bearing capacity of CFDST sections.
