“…Concrete-filled steel tube (CFST) has been applied widely in civil engineering for many years. To this date, there have been a number of studies conducted to investigate the behaviour of CFST columns (Ou et al 2011). The main benefit of using CFST is that it utilises the advantages of both steel and concrete, viz.…”

This paper concentrates on the compressive bearing capacity of one composite column of a Concrete-Filled Square Steel Tube (CFSST) reinforced by a circular steel tube inside. Some tests were conducted to consider the compression behaviour of the stub columns under axial compressive loading. Through an elastoplastic limit analysis based on Unified Strength Theory (UST), the ultimate load capacity of the CFSST columns reinforced by inner circular steel tube under axial compression has been derived, which has a good agreement with the experimental results in comparison with other empirical models. So this model is extended to predict the optimal design of the inner tube, namely, Di/ti and Di/B. In addition, another simple model is also proposed to testify the optimal section of this composite column. With the optimal circular steel tubes inside the CFSST column, the composite column can result in significant savings in column size, which ultimately can lead to significant economic savings and higher bearing capacity. The results show that it has a theoretical significance and application value to adopt circular steel tube to strengthen CFSST column.

“…For the concrete-filled steel tubular (CFST) structure, it is well known that the mechanical properties are of great importance. Some investigations have been performed to reveal the mechanical properties of the CFST structure with different shapes (rectangular, square, or circular) by using various test (axial compression test, biased compression test, and torsion test) [5][6][7][8][9][10][11][12][13][14]. e results showed that the overall performance of the CFST structure was excellent, and the steel tube composite members can be applied to engineering practice.…”

In this paper, a new steel-wood composite column with an H-shaped section was proposed. In order to form an H-shaped cross section, a larch board is fixed on the outer surface of the left and right edges of a hot-rolled H-beam by using physical connection. When the eccentricity is the same, eccentric compression tests were carried out on two types of columns by changing the thickness of the larch board, cross-sectional area of the hot-rolled H-beam, and slenderness ratio in composite columns. Therefore, type A is joined by structural glue only with the larch board and hot-rolled H-beam, and type B is joined by both structural glue and bolts. With the variation of strain and deflection, failure process and failure modes of the hot-rolled H-beam and larch from composite columns under various loads were observed, and the ultimate bearing capacity and stability of composite columns were studied. The test results showed that the overall working performance of the hot-rolled H-beam and larch board was good, and the stability of the hot-rolled H-beam column could be effectively improved. With the increase of wood thickness, cross-sectional area of the hot-rolled H-beam, slenderness ratio of composite columns, and the bearing capacity of the specimens were increased. Moreover, a simplified formula was proposed by the superposition principle. The theoretical analysis accorded with the experimental results, thus providing a reference basis for further study and application of similar steel-wood composite columns.

“…In addition, the use of CFST columns can bring convenience to construction due to the absence of formwork. In the past few decades, a significant number of experimental and analytical studies into the structural behaviour of CFST columns have been carried out [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In these studies, it was shown that confinement to the concrete in circular CFST columns brings substantial benefit in terms of load-bearing capacity, but that this effect degrades dramatically upon yielding or local buckling of the steel tube.…”
