Tests on fiber reinforced concrete filled steel tubular columns

Experimental behaviour of eccentrically loaded slender circular hollow steel columns in-filled with fibre reinforced concrete

“…The purpose of this study was to examine the effects of FRC on the strength and behaviour of slender composite columns. The studies carried out by the authors in the last few years on the influence of FRC on the behaviour of such columns have shown that the addition of steel fibres in the core concrete does not seem to have any effect on the load bearing capacity of stub and short columns [7]. Some of the test results on slender columns with partially fixed end conditions were also reported in the paper.…”

Seismic Performance of Exterior Steel Ring‐Stiffener Joint

“…e recycled-concrete-filled steel-tube column inherits the advantages of high bearing capacity, good seismic performance, and convenient construction of CFST columns. e literature [2][3][4][5][6][7][8][9][10][11][12] reveals that the performance of CFST can be improved by adding steel fibres to the concrete, and that this technical method could have broad applications in high-rise buildings and large-span structures. Research also shows that the recycled-concretefilled steel tubes can meet the performance of an ordinary steel tube under most conditions.…”

“…Yin [3] studied the axial compressive properties of steel-fibre-lightweight-aggregate-concrete-filled steel tubular column by exposing it to flames. Gopal and Manoharan [4] conducted an experimental study on the eccentrically compressed, fibre-reinforced-concrete-filled slender circular steel tubes.…”

Behavior of steel fiber reinforced concrete-filled steel tube columns under axial compression

“…In recent years, the behavior of fiber reinforced concrete-filled steel tube columns at room temperature has been an increasing concern. The behavior of steel tube columns filled with fiber reinforced low, and normal strength concrete have been investigated by Campione et al [16,17], Gopal and Manoharan [18], Ellobody and Ghazy [19], Ellobody [20,21], Tao et al [22] and Gopal [23]. In those studies, the CFST columns were of slender columns or/and tested under eccentrically load, and the enhanced flexural and tensile strengths of fiber reinforced concrete were applied to ease the increasing strain gradient associated with increasing flexure.…”
