Concrete-filled elliptical hollow section (CFEHS) beam-columns modelled numerically. Extensive parametric study varying key variables across 360 specimens conducted. Results compared to current Eurocode 4 rules for circular and rectangular members. Current rules are suitable for columns in combined compression and uniaxial bending. Recommend to use buckling curves b and c for columns in axial compression.
