The behavior of concrete filled steel tubular (CFST) elements with different types of stiffening
measures has been wildly investigated during the past two decades through experimental …

For any structures, Reinforced concrete (RC) columns are the utmost carping members. RC
columns jacketed with CFRP membrane enhance resistance, deformation aptitude, and the …

The use of the circular hollow steel tube in a circular concrete-filled steel tubular (CFST)
column significantly alters the confinement mechanism in the conventional CFST column …

In this study, compressive strength, modulus of elasticity and steel tensile coupon tests are
performed to determine material properties. Sixteen hollow cold formed steel tubes and 48 …

Proper material constitutive models for concrete-filled double skin tube (CFDST) columns
with circular cross-section and subjected to axial compressive forces are proposed and …

Experiments show that the ultimate compressive strength of stainless steel is much higher
than its tensile strength. The full-range two-stage constitutive model for stainless steels …

This paper presents the behaviour of the composite frame with concrete-filled square hollow
section (SHS) columns to steel beam. Finite element modeling (FEM) was developed to …

The casting of concrete in concrete-filled steel tube (CFST) can, via the confinement effect of
the steel tube, significantly increase the ductility of the concrete and, in the case of high …

Rectangular concrete-filled steel tubes (RCFST) are efficient structural members that exhibit
good strength, stiffness, and ductility. The mechanical properties of RCFST can be further …

Thin-walled square concrete filled steel tubular (CFST) members have attracted more
attention in practice because of less steel consumption, high construction efficiency, and …
