The typical failure mode of the composite column was local failure mechanism as shown in Figure 3.
The composite column was divided into four parts outer steel tube, inner steel tube, outer concrete and inner concrete in order that every part would be conducted by elastoplastic analysis, respectively.
Results of dispersion analysis of composite column
load bearing capacity are summarized in Table 1.
The cause of failure of the composite column
, in which axial force was applied to the whole surface of section, was due to concrete crushing in the upper supporting zone (Fig 4).
Tapered concrete-filled steel composite columns
can be used for high and low rise buildings because of their large load carrying capacity and high ductility.
More specifically, it is - Traction posts and composite columns
pull-lighting- Signposts for the placement of vertical road signs,- Signal terminal 19 galvanized studs,- 76 mm poles with cross was mounted with eye and base,- 76 mm mounted on poles was sightless and base,- 76 mm signposts,- Accessories.

An extensive variety of composite columns
are available nowadays, but the concrete filled steel tubular (CFST) sections are most commonly used.
Significantly revised chapters on columns, plates, composite columns
and structural systems, frame stability, and arches
Local and interaction buckling in composite columns
2004) on steel tubular columns of square, rectangular and circular sections filled with normal and lightweight aggregate concrete were conducted to investigate the failure modes of such composite columns
These composite columns
can be also used for the resisting outside pressure, such as ocean waves, ice; in seismic regions because of excellent earthquake-resistant properties such as high strength, high ductility, and large energy absorption capacity.
