Test results of common specimens.

Specimen number	D (mm)	t (mm)	L (mm)	Section type	Steel casing	Fu (kN)	Fud (mm)
NC1	165	1.2	1200	Concrete section	Y	130.00	7.1
NC2	165	1.6	1200	Composite section	Y	177.00	6.4
NC3	165	1.2	1200	Composite section	Y	160.00	5.8

Note. D: sectional diameter of the circular steel tube; t: wall thickness of the steel tube; L: length of the specimens; composite section: reinforced concrete cross section; concrete section: concrete cross section; F_u: ultimate bearing capacity of the concrete-filled steel tube; F_ud: ultimate deformation of the concrete-filled steel tube.
