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 ...

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.

Axial performance of GGBFS concrete filled steel tubes

Structures, 2020
Abstract Fifteen circular concrete-filled-steel tubes (CFST) containing ground granulated blast furnace slag (GGBFS) concretes were tested in axial compression. CFST columns were casted with four concrete mixtures having 0, 15, 25 and 35% GGBFS replacement levels and two different length-to-diameter ratio of 2.87 and 4.

Flexural response of concrete-filled seamless steel tubes

Journal of Constructional Steel Research, 2018
Abstract This paper aims to investigate the flexural behavior of concrete filled tubes (CFSTs) made of seamless steel which can handle more pressure than welded steel. Experimental, Theoretical and Finite Element Analyses are utilized for this purpose.

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 ...

Behavior of Concrete-Filled Steel Tube Beam Columns

Journal of Structural Engineering, 2004
The behavior of concrete-filled circular and square steel tubular (CFT) beam columns with a variety of material strengths was investigated experimentally. The main test parameters are steel strength (400, 590, and 780 MPa), diameter- (width-) to-thickness ratio of steel tube, and concrete strength (40 and 90 MPa).

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 ...

Numerical analysis of concrete-filled circular steel tubes

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2013
Concrete-filled steel tubes have been widely used in building and bridge construction. In this paper, the flexural behaviour of concrete-filled steel tubes is investigated using finite-element analysis and theoretical sectional analysis. The numerical results from both analytical methods are validated against published experimental test results. It is

Polymer concrete-filled steel tubes under axial compression

Construction and Building Materials, 2001
Abstract Concrete-filled steel tubular (CFT) structures are rapidly emerging as one of the inevitable structural systems for earthquake resistance, as they have been known to exploit the best attributes of both steel and concrete, resulting in higher stiffness, strength and ductility.
