This paper deals with the ultimate load capacity test on 14 short columns of separation concrete-filled steel tubes (CFST) which are subjected to the eccentric compression on separate side. The experimental parameters include the separation ratio and the eccentricity ratio. The result shows that the separation ratio and the eccentricity ratio will influence the load capacity of the components of the concrete-filled steel tubes which are subjected to the eccentric compression. The confinement of steel tubes to core concrete will be continuously weakened and the ultimate load capacity of the components will be decreased obviously with both the separation ratio and the eccentricity ratio increasing gradually.

Compressive Tests

By means of axial compressive and eccentric compressive tests of four Four-tube Concrete-filled Steel Tubular Laced Columns, to research the mechanical properties and failure modes of this structural without yield point. Research shows that, the failure modes of this model, as well as axial compressive short columns, have the same trend of oblique shear failure, and presenting overall bending failure under eccentric compression. The linear eccentricity takes a biggish influence on mechanical properties of laced columns.

Adverse Influence

For the eccentric compression structures which cannot be strengthened by wrap method, this paper presents an experimental and numerical study on flexural strengthening by applying textile reinforced concrete at the tensile face. Seven short columns were constructed and tested under eccentric load. One of the columns did not receive any strengthening and was used as the control column, whereas the rest six were externally upgraded by textile-reinforced concrete layers. The main parameters taken into account covered: (a) type of mortar, (b) preload level, and (c) number of textile-reinforced concrete layers. Besides the experimental program, a numerical investigation utilizing non-linear finite element analysis was carried out and a good agreement was obtained between the experimental and numerical results. Further, the numerical analysis was extended to additional cases to deepen the understanding of flexural-enhancing mechanism . It is concluded that textile-reinforced concrete substantially increases the flexural capacity of the eccentric compression columns; the more the textile layer, the greater the gain. However, the preload has an apparently adverse influence on the strengthening effectiveness, as it causes the strain loss of the textile; the bigger the preload level, the more the loss.

This document deals with the whole process compression model test on 12 short columns of separation concrete-filled steel tubes (CFST) which are subjected to eccentric compression on the non-separation side. The experimental parameters include the separation ratio and the eccentricity ratio. The results show that the separation ratio and the eccentricity ratio will influence CFST components’ mechanical properties which contain the relationship of load-strain amd load-deformation, that especially embodied in the nonlinear stage. When compressed on non-separation side, the confinement of steel tubes to core concrete will be continuously weakened and the ultimate load capacity of the components will be decreased obviously with both the separation ratio and the eccentricity ratio increasing gradually. But it less serious which compare with that compressed on separation side.
