title = "Concrete-filled double-skin circular tubes with high strength concrete",
abstract = "The use of high strength concrete in high-rise structures has been rapidly increasing worldwide. The benefit of using high strength concrete in these structures is centered on the reduction of the member size, which ultimately leads to an increase of the floor space and a decrease of the size of the foundation. Six concrete-filled double-skin (CFDSCTs) were tested in axial compression until failure. The slenderness ratios were varied. High strength concrete of 52 MPa concrete was used. The 1m columns failed by local buckling while the 1.5, 2 and 2.5 meter columns all failed by overall flexural buckling. The test results indicate that the columns all acted compositely. Axial capacity equations for high concrete strength CFDSCT are proposed based on the experimental results.",
