Abstract (en)

There is disclosed a concrete filled tube column which includes: an outer tube (42) connected to beams of the structure so that an axial load is transferred from the beams and applied to the outer tube (42), the outer tube (42) consisting of a plurality of tube pieces (46) coaxially disposed in series, the tube pieces (46) having substantially equal transverse inner sizes; a concrete core disposed within the outer tube (42); and a tubular member (62), coaxially fitting within each of the tube pieces (46), for transferring the axial load from the outer tube (42) to the concrete core. The tubular member (62) has a constant transverse outer size and a lower end portion. The lower end portion of the tubular member (62) has a first inner peripheral face tapering upward so that the transverse inner size at the lower end of the tubular member is equal to the transverse inner size of each of the tube pieces.
