Bond behavior in concrete-filled steel tubes
Journal of Constructional Steel Research, 2016Abstract 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, 1998This 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.

Stiffened concrete-filled steel tubes: A systematic review
Thin-Walled Structures, 2020Abstract The behavior of concrete filled steel tubular (CFST) elements with different types of stiffening measures has been wildly investigated during the past two decades through experimental, analytical, and numerical approaches. The previous studies highlighted the importance of the presence of internal and external stiffeners to enhance the ...

Axial performance of GGBFS concrete filled steel tubes
Structures, 2020Abstract 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.

STUDY ON CONCRETE FILLED STEEL TUBE
2023ABSTRACT The objective of the continuous survey is to grasp how a steel tubular segment heaped with concrete tends to a vital weight. A steel tube is filled with concrete to make a concrete-filled steel tubular (CFST) fragment. Because of their phenomenal static and quake safe qualities, for example, high strength, high adaptability, tremendous energy ...
