Bond behavior in concrete-filled steel tubes

Journal of Constructional Steel Research, 2016
Abstract In this paper, the bond behavior between the steel tube and the concrete in concrete-filled steel tubes (CFST) is investigated. A series of push-out tests on circular and square CFST specimens were conducted, and the main parameters considered in the test program were: (a) cross-sectional dimension (120–600 mm); (b) steel type (carbon and ...

Axially Loaded Concrete-Filled Steel Tubes

Journal of Structural Engineering, 1998
This paper presents an experimental and analytical study on the behavior of short, concrete-filled steel tube columns concentrically loaded in compression to failure. Fourteen specimens were tested to investigate the effect of the steel tube shape and wall thickness on the ultimate strength of the composite column.

Axial behaviour of slender concrete-filled steel tube square columns strengthened with square concrete-filled steel tube jackets

Advances in Structural Engineering, 2019
This article investigates the behaviour of slender concrete-filled steel tube square columns strengthened by concrete-filled steel tube jacketing. The columns were realised by placing a square outer steel tube around the original slender concrete-filled steel tube column and pouring strengthening concrete into the gap between the ...

Research and practice of concrete-filled steel tubes in Lithuania

Journal of Constructional Steel Research, 1999
Abstract The research and practice of concrete-filled steel tubular members in Lithuania are described. Attention is especially paid to more effective super-thin and thin-walled concrete-filled steel tubes incorporating hollow concrete cores formed by centrifugal force.

Flexural behaviour of concrete-filled steel tubes

Journal of Constructional Steel Research, 2004
Abstract This paper develops a mechanics model that can predict the behaviour of concrete-filled hollow structural section (HSS) beams. A form of unified theory, where a confinement factor (ξ) was introduced [Steel Compos. Struct.—Int. J. (2001) 1(1) 51] to describe the composite action between the steel tube and filled concrete, is used in the ...

CONNECTION OF STEEL BEAMS TO CONCRETE-FILLED TUBES

2004
Abstract Tests have been carried out on twentyeight connection specimens. The specimens consisted of steel beams connected to columns made of concrete-filled steel tubes. The results reported here are for a series of eight specimens in which the columns were made of a steel rectangular hollow section 150x150x5 RHS.

Overview of Concrete Filled Steel Tube Viod Countermeasures

Applied Mechanics and Materials, 2012
We found through the statistics of disease that the void is one of the major problems of the CFST in recent decades. In fact, the void is inevitable with the current state of materials and construction method. This paper describes detailedly many methods of repairing void from the two aspects of the existing bridge and the under-construction bridge ...

Beam-column behavior of concrete filled steel tubes

Steel and Composite Structures, 2002
In the present investigation the experimental and theoretical flexural and compressive behavior of short tubular steel columns filled with plain concrete and fiber-reinforced concrete (FRC) was examined. For a given length of the members, the effects of different geometry and dimensions of the transverse crosssectionrn(square and circular) were ...

Analysis of the Concrete Filled Steel Tubes with Diagonal Ribs

2020
Nowadays high-rise buildings and multi-storey buildings are more common and popular, they require highly strong and efficient structural system. Concrete Filled Steel Tube [CFST] are capable of providing the same. Many innovative ideas are being put forward in the improvement of the CFST section, which resulted in better improvisation of their column ...

Behavior of Circular Concrete-Filled Steel Tube Columns

Composite Construction in Steel and Concrete IV, 2002
The behavior of concrete filled tube columns under seismic loads was studied through testing six columns which were subjected to a constant axial load in addition to a cyclic lateral load. The test parameters included the level of axial load, the diameter-to-thickness ratio of the steel tube, and the concrete strength.
