This paper presents a test campaign concerning the behavior of concrete-filled cold-formed
steel built-up section stub columns. The test program consisted of five types of cold-formed …

This paper is an attempt to investigate the structural behavior of concrete-filled cold-formed
steel stub columns with semi-oval cross sections via experimental and numerical studies …

This paper summarizes the latest technical and scientific progresses on steel-concrete
composite structures exposed to fire, presenting the recent research carried out on this …

A comprehensive experimental and numerical study of concrete-filled double skin tubular
(CFDST) stub columns is presented in this paper. A total of 23 tests was carried out on …

Abstract Concrete-filled-steel-tube (CFST) and double-skinned concrete-filled-steel-tube
(DSCFST) columns have superior strength, stiffness and ductility to that of traditional …

This paper aims to study the structural performance and design of cold-formed steel elliptical
hollow sections under combined compression and minor axis bending. An accurate finite …

An experimental study on cold-formed steel elliptical hollow section (EHS) beam-columns is
described in this paper. Forty-two beam-column members with two different specimen …

Tubular steel members with slender cross-sections in compression are prone to local
buckling. Different approaches, such as infilling concrete, installation of internal stiffeners …

A comprehensive experimental and numerical study of the cross-sectional compressive
behaviour and resistances of press-braked S960 ultra-high strength steel (UHSS) angle and …

The use of concrete-filled double skin tubular (CFDST) cross-sections for compression
members has become increasingly popular in construction. A recently proposed innovative …
