Fire performance of concrete-encased CFST columns and beam-column joints [PDF]
Proceedings 12th international conference on Advances in Steel-Concrete Composite Structures - ASCCS 2018, 2018 Concrete-encased CFST (concrete filled steel tube) structure is a type of composite structure featuring an inner CFST component and an outer reinforced concrete (RC) component. They are gaining popularity in high-rise buildings and large-span buildings in China nowadays.

CFRP strengthened CFST columns under vehicular impact [PDF]
Proceedings of the Second International Conference on Performance-based and Life-cycle Structural Engineering (PLSE 2015), 2015 Concrete filled steel tubular (CFST) columns are increasingly used in bridge piers and high-rise buildings due to their excellent axial load bearing capacity. These columns may experience severe damage or failure due to transverse impact of vehicle collisions.

Evaluation of Eccentric Compressive Behavior Between Active and Passive Preloading in CFST
Applied SciencesConcrete-filled steel tubes (CFSTs) are widely used in high-rise buildings and bridges, owing to their confinement effect on concrete. The confinement effect can enhance the compressive strength and ductility of the components. During the construction of

Axial Compression Behavior of Concrete-Encased CFST Columns
Civil Engineering JournalComposite construction known as concrete-encased CFST is an outer covering of concrete surrounding a steel tube filled with concrete. It is employed as a structural member in multi-story buildings, large structures, bridges, and underground subway systems. Most of the literature deals with steel tubes filled with core concrete or concrete-encased steel

Constitutive relation of stiffened square CFST Columns
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Using the constitutive model of a square CFST column with binding bars, the constrained mechanism of the stiffened square CFST columns is analyzed in great detail. The equivalent constitutive model under uniaxial compression is established for square CFST columns.
