The main objective of the present work is to estimate the load-carrying capacity of concrete-
filled steel tubes (CFST) under axial compression using hybrid artificial intelligence (AI) …

Abstract Concrete Filled Double Skin Steel Tube (CFDST) columns which comprise two
concentric steel tubes and shell concrete between them is a favourable member of …

To investigate the influence of circumferential gap on the impact-resistance capacity of CFST
columns, 12 CFST specimens were tested under constant axial load and lateral impact …

With the continuing developments in composite design technology, such as classical
Concrete Filled Steel Tubes (CFST), concrete filled double skin tubes and concrete filled …

This paper presents a review on the axial compression behavior of different cross-sectional
shaped concrete-filled steel tube (CFST) columns such as circular, rectangular, square …

Concrete-filled elliptical steel tube (CFET) is a novel type of composite member, which has
great potential to be used as piers and columns in bridges and airport terminals because of …

Utilizing manufactured sand (MS) with high content of stone dust, mix proportion tests were
carried to investigate the influence factors of preparing self-compacting concrete (SCC) with …

Recently, many researchers have shown a great interest in single skin concrete-filled steel
tubular (CFST) columns with circular and rectangular sections, as well as elliptical sections …

Elliptical concrete-filled steel tubular (CFST) columns have recently attracted significant
attention because of their increased strength and stiffness compared with empty elliptical …

Experimental and numerical studies were conducted to investigate the behaviours of the
concrete-filled cold-formed elliptical hollow section beam-columns. A total of 11 specimens …
