Axial compressive behaviour of high-strength steel spiral-confined square concrete-filled steel tubular columns

Fang Yuan et al.

Summary: The axial compressive performance of high-strength steel spiral-confined square CFST columns was experimentally investigated, and it was found that increasing the volume of the internal steel spiral can significantly enhance the ductility and strength of square CFST columns. There exists a strong interaction between the confinement contribution made by the internal steel spiral and that provided by the outer steel tube.

Effect of high-strength spirals on eccentric compression behavior of square CFST columns

Fang Yuan et al.

Summary: This study systematically investigated the eccentric compressive performance of square CFST columns with high-strength internal spirals (HSS). It was found that the strength and ductility of the columns were significantly improved by incorporating the contribution of the confined HSS. Detailed finite element analyses revealed that the internal spirals enhanced the axial stress of the confined concrete and improved the interaction between the concrete and steel tube. Decreasing the steel spiral pitch improved the strength and ductility of the columns more effectively than increasing the diameter of the steel spiral. Design recommendations for eccentrically loaded spiral-confined square CFST columns are provided.

Compressive behavior of concrete-filled steel tubular columns with internal high-strength steel spiral confinement

J. G. Teng et al.

Summary: The study investigates a new form of concrete-filled steel tubular (CFST) columns known as confined concrete-filled steel tubular (CCFST) columns, which exhibit greater ductility and lower steel volume consumption compared to traditional CFST columns. Experimental results show that the axial load-axial strain curve of a CCFST column can be conservatively predicted by combining the curves of a hollow steel tube, HSS spiral-confined concrete core, and sandwiched concrete.

Mechanical behavior of spiral stirrup reinforced concrete filled square steel tubular columns under compression

Zongping Chen et al.

Summary: This paper presents an experimental study on compressive behavior of spiral stirrup reinforced concrete-filled square steel tubular (SSRCFSST) columns. The test results show that the spiral stirrup has excellent cooperation ability with square steel tube and concrete, and decreasing the spacing of spiral stirrup can enhance the axial bearing capacity and ductility of SSRCFSST columns. A composite model confined by square steel tube and spiral stirrup is established, with close correlations found between the calculated results and the experimental results.

Seismic behavior of terminal stirrup-confined concrete-filled elliptical steel tube columns: Experimental investigation

Tao Zhang et al.

Summary: Concrete-filled elliptical steel tubes, as a new member of the CFT structural families, have great potential for use as piers and columns in bridges and airport terminals due to their low flow resistance coefficient and reasonable distribution of major-minor axis. Experimental investigation showed that using stirrups in CFET columns can directly confine the core concrete, enhancing the seismic behavior significantly, especially under higher axial load ratios.
