“…In the last few decades, high-rise, large-span, and large-scale building structures have become more common. Concretefilled steel tubular (CFST) members are well recognized for their excellent performance owing to the combined merits of steel and concrete materials [1]. erefore, concrete-filled steel tubes are being increasingly used in high-rise buildings and in large-span structures.…”

The behavior of concrete-filled steel tube (CFST) columns subjected to axial compression was experimentally investigated in this paper. Two kinds of columns, including CFST columns with foundation and columns without foundation, were tested. Columns of pure concrete and concrete with reinforcing bars as well as two steel tube thicknesses were considered. The experimental results showed that the CFST column with reinforcing bars has a higher bearing capacity, more effective plastic behavior, and greater toughness, and the elastoplastic boundary point occurs when the load is approximately 0.4–0.5 times of the ultimate bearing capacity. The change of rock-socketed depth and the presence of steel tube will affect the ultimate bearing capacity of rock-socketed pile. The bearing capacities of the rock-socketed CFST columns are lower than those of rock-socketed columns without a steel tube under a vertical load; besides, the greater the rock-socketed depth, the greater the bearing capacity of the rock-socketed piles. In addition, a numerical comparison between the ultimate load and the theoretical value calculated from the relevant specifications shows that the ultimate load is generally considerably greater than the theoretical calculation results.

Summary To study the seismic behavior of specially shaped concrete‐filled tube (CFT) columns with multiple cavities under axial tension or axial compression, a quasistatic test of four 1/30‐scale specially shaped CFT columns with multiple cavities was conducted based on the CFT mega columns in a super‐high‐rise building. The main parameters of the 4 specimens were the direction of axial force, the direction of horizontal force, and the cross‐sectional structural form. The test was conducted twice at each level of horizontal displacement. The results shows that the compression–flexure test specimen showed lower yield damage, higher bearing capacity, and superior seismic performance relative to the tension–flexure test specimen; the specimen loaded along the short axis of the section had a lower bearing capacity and stiffness relative to the specimen loaded along the long axis; and the corner‐reinforced specimen with a round steel pipe was found to be rationally designed and properly constructed. Finally, an N–M correlation curve was generated and found to show satisfactory agreement between the fitted values and the test values.
