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 ...

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.

Behavior of Steel Tube and Confined High Strength Concrete for Concrete-Filled RHS Tubes

Advances in Structural Engineering, 2005
This paper presents an experimental study of the separated behavior of short ( L/H=3) high strength concrete-filled rectangular hollow section (RHS) tubes concentrically loaded in compression to failure. A total of 50 specimens were tested. Experimental results showed that the concrete strength influenced the failure pattern of the specimen. The height-

Optimum concrete filling ratio for partially filled noncompact steel tubes

Thin-Walled Structures, 2019
Abstract In this study, both experimental and analytical investigations have been carried out on noncompact Circular Hole Section (CHS) steel tubes with partial concrete filling. A total of nine specimens are tested as cantilever under flexural loading.

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.

The Influence of Concrete Compaction on the Strength of Concrete Filled Steel Tubes

Advances in Structural Engineering, 2000
Tests on twenty-one concrete filled steel tubes to investigate the influence of compaction methods on the strength of concrete filled steel tubular members are reported. Two parameters were investigated, including slenderness ratio and load eccentricity.

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 ...

A Review of Concrete-Filled Steel Tube Elements

2021
Structural elements such as composite columns and beams filled with concrete compared to reinforced concrete elements, maintenance-free concrete inside the pipe, being able to pour concrete without molds, having high rigidity and strength, increasing the strength of the concrete inside the pipe by limiting the lateral deformations and pressure elements

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 ...
