Behavior of FRP Ring-Confined CFST columns under axial compression

, 2021
Although concrete-filled steel tube (CFST) columns have been widely accepted in applications, they suffer deterioration due to various reasons. On the other hand, the concrete and the steel in CFST columns subjected to compression are not perfectly ...

Formulation of stress concentration factors for concrete-filled steel tubular (CFST) T-joints under axial force in the brace

, 2018
CFST T-joints consisting of a concrete-filled circular chord and a circular hollow section brace have been used in CFST trussed arch bridges. The stress concentration factors (SCFs) of CFST T-joints have been found to be much lower than those of circular

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.

Fire Exposure Behavior of CFST Column

International Journal of Innovative Technology and Exploring Engineering, 2019
From the past numerous years Concrete Filled Steel Tubes (CFST) segments are progressively utilized in the structures on account of their high burden bearing limit. In CFST sections the solid is encased in a steel tube that gives formwork to solid which aides in continuing the nearby clasping of the steel. Additionally, composite sections will add more
