Concrete-Filled Steel Tube Columns Encased with Thin Precast Concrete

Journal of Structural Engineering, 2015
AbstractAn experimental study was performed to investigate the axial-flexural load-carrying capacity of concrete-filled steel tube columns encased with thin precast concrete (PC). Six eccentrically loaded columns and one concentrically loaded column were tested.

Concrete Filled Steel Tube Piles to Concrete Pile-Cap Connections

Structures Congress 2012, 2012
This paper describes preliminary findings from a Montana Department of Transportation (MDT) funded project focused on testing the seismic performance of concrete filled steel tube (CFT) pile to concrete pile-cap connections. These connections are common/critical components of the support structure for highway bridges in Montana and across the country ...

CFRP-reinforced concrete-filled steel tubes with timber core under axial loading

Composite structures, 2019
This paper experimentally investigates the effect of Carbon Fibre Reinforced Polymer (CFRP) on the axial capacity of concrete-filled steel tubes with different timber cores. The stub columns were designed having the size of the infill and the CFRP as the

Behavior of concrete-filled steel tubes subjected to axial impact loading

, 2020
Investigations on concrete-filled steel tubular (CFST) members under static loads have been extensively reported. Still, limited researches have been conducted to investigate the behavior of CFST columns subjected to axial impact loading.

Concrete-Filled Steel Tubes for Accelerated Bridge Construction

Transportation Research Record: Journal of the Transportation Research Board, 2014
Concrete-filled steel tubes (CFSTs), which are steel tubes with concrete infill, have increased strength, stiffness, and deformability relative to comparably sized reinforced concrete columns. The steel is at its optimal location and thus maximizes strength and stiffness while minimizing weight and material requirements and providing confinement to ...

Influence of concrete mix proportions on axial performance of concrete-filled steel tubes made with self-compacting concrete

Advances in Structural Engineering, 2020
Self-compacting concrete is quite commonly used in concrete-filled steel tube structures, but the compaction level of the self-compacting concrete, that is, the percentage of volume occupied by materials other than air void, within the steel tube is ...

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 ...

Eccentric compression performance of slender L-shaped column composed of concrete-filled steel tubes connected by steel linking plates

Journal of constructional steel research, 2019
To study the uniaxial eccentric compression properties of slender L-shaped column composed of concrete-filled steel tubes (CFST) connected by steel linking plates, a compression test on four L-shaped CFST columns with different eccentricities was ...

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 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.
