Finite element analysis of concrete-filled steel tube (CFST) columns with circular sections under eccentric load [PDF]
Engineering Structures, 2017 The casting of concrete in concrete-filled steel tube (CFST) can, via the confinement effect of the steel tube, significantly increase the ductility of the concrete and, in the case of high-strength concrete (HSC), alleviate the shortfall in ductility of the HSC. This kind of structure is gaining popularity but its behaviour is quite complicated. In an

Journal of Constructional Steel Research, 2013
Abstract This paper presents an experimental study to investigate the compressive behavior of circular concrete filled steel tubes (CFSTs) when subjected to pure axial loading at a low rate of 0.6 kN/s. CFSTs of three different diameter-to-thickness ( D t ) ratios of 54, 32, and 20 are considered in this study filled with two concrete's ...

Application and Development of Concrete-Filled Steel Tubes (CFST) in High Rise Buildings
Advances in Structural Engineering, 1999In recent years, theoretical research achievements in China have clearly showed the advantages of CFST members. Especially they have a better aseismic performance than steel structures. In addition, for high-rise buildings, the wall of the steel tubes used in CFST structures are much thinner plate than that of normal steel columns.

Abstract This paper presents an advanced finite element analysis (FEA) model to predict the fire behaviour of concrete-encased concrete-filled steel tube (CSFT) columns. The sequentially coupled thermal-stress analysis method provided in the software package ABAQUS was used.

Abstract This study aims to provide numerical formulation of the behavior of the compact concrete-filled steel tubes (CFSTs) based on constraints with the tie model permitting the two regions to fuse together. This study defined the interface between steel tubes and concrete cores with tie parameters allowing only rotation at the interface. Nonlinear

Abstract The confinement provided in concrete-filled steel tube (CFST) columns can significantly increase the strength and ductility of the concrete columns. However, in non-circular CSFT, the confining stresses are non-uniform and anisotropic, making their incorporation in structural analysis and design fairly difficult.

Compressive performances of concrete filled Square CFRP-Steel Tubes (S-CFRP-CFST)
Steel and Composite Structures, 2014Sixteen concrete filled square CFRP-steel tubular (S-CFRP-CFST) stub columns under axial compression were experimentally investigated. The experimental results showed that the failure mode of the specimens is strength loss of the materials, and the confined concrete has good plasticity due to confinement of the CFRP-steel composite tube. The steel tube

Gap between steel tube and concrete core could be recognized as a type of initial concrete imperfection in concrete-filled steel tubular (CFST) members. This paper is an attempt to study the effect of gap on the behaviour of concrete-filled steel tubular (CFST) columns subjected to eccentric compression.

Abstract This paper studies the flexural behavior of circular concrete filled steel tubes (CFST) under sustained load and chloride corrosion. 7 CFST specimens were tested under a four-point bending load. It was found that corrosion causes noticeable deterioration to the flexural strength, while the ductility of CFST keeps well.
