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 ...

Behavior of square hollow steel tubes and steel tubes filled with concrete

Thin-Walled Structures, 2007
Abstract This paper investigates the occurrence of local buckling in bare steel and concrete-filled tubes to study how different depth-to-thickness ratios affect the response of the steel component. The experimental set-up and results of 24 tests are presented in this paper.

Evaluation of concrete–steel interfaces in steel tubes filled with chipped rubber–concrete

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2023
The objective of this study was to evaluate the bond behaviour of concrete-filled steel tubes (CFSTs) where waste chipped rubber, sourced from scrap tyres, partially replaces natural coarse aggregate. A series of push-out tests on 112 circular and square CFST specimens were investigated with the main parameters considered in the tests being: (a) cross-

Bond properties of steel angles in concrete filled steel tubes

Journal of Constructional Steel Research, 2021
Abstract The performance of concrete filled steel tubes (CFSTs) in tensile actions can effectively be improved by inner steel L-profiles embedded in the core concrete. In order to investigate the bond properties between the steel angle and core concrete, 24 pull-out specimens with variable bond length and cross-section area were tested.

Creep modeling for concrete-filled steel tubes

Journal of Constructional Steel Research, 2003
Using the rate of flow method and the double power law function for basic creep of concrete, an algorithm is developed for the time-dependent behavior of concrete-filled steel tube (CFT), with or without the interface bond. The model adheres to geometric compatibility and static equilibrium, and considers the effects of sealed concrete, multi-axial ...

Flexural performance of concrete-encased concrete-filled steel tubes

Magazine of Concrete Research, 2014
The flexural performance of concrete-encased concrete-filled steel tubes (CFSTs) was investigated. A finite-element analysis (FEA) model is developed to analyse the flexural behaviour of the composite member and a set of test data used to verify the FEA modelling.

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.

Study on Usage of Expansive Concrete in Concrete Filled Steel Tube

2010 International Conference on Challenges in Environmental Science and Computer Engineering, 2010
As a promising green material in civil engineering construction, concrete filled steel tube has attracted an increasing attention. However, there may be vibrating imperfect in the construction progress and concrete shrinkage in the hydration process. Thus the application of concrete filled steel tube is not widely in practical engineering.
