Structural behaviour of circular concrete filled steel tube column fill with selfcompacting concrete incorporating coal bottom ash as fine aggregate replacement [PDF]
, 2019 Lack of compaction may affect the interaction between the steel tube and the concrete, hence influence the behaviour of CFST column. Employing selfcompacting concrete (SCC) in CFST column as an infill concrete remove the necessity for compaction ...

Tensile Behavior of Concrete‐Filled Steel Tubular Column Splices Using Perforated Steel Plates
JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.This study proposes a CFST column splice design transferring stress through infilled concrete using welded perforated steel plates. Pull‐out tests on the perforated steel plates were conducted to develop a strength prediction formula, which was validated through tensile experiments on column splices and predicted their tensile capacity.

Concrete-encased CFST structures: behaviour and application
Proceedings 12th international conference on Advances in Steel-Concrete Composite Structures - ASCCS 2018, 2018 Concrete-encased CFST (concrete-filled steel tube) is a kind of composite structure comprised of a CFST component and a reinforced concrete (RC) component. The concrete encased CFST possesses superior ductility and higher stiffness. They are gaining popularity in high-rise buildings, large-span structures, bridges, subway stations and workshops.

Cyclic Behavior of Square CFST Columns-Based Joint
Advances in Civil Engineering, 2023 This paper investigates the cyclic behavior of six square concrete-filled steel tube (CFST) columns that take the effect of width–thickness ratio (D/t = 30, 40, and 60), slenderness ratio (λ = 19.63 and 24.25), and axial force ratio (n = 0.6, 0.4, and 0.2) into consideration.
