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 …

The state of the art of concrete-filled steel tubular (CFT) columns including experimental and
analytical work is presented in this paper. The general response of CFT columns is …

External confinement of concrete by means of high-strength fiber composites can
significantly enhance its strength and ductility as well as result in large energy absorption …

Proper material constitutive models for concrete-filled tube (CFT) columns are proposed and
verified by the nonlinear finite element program ABAQUS against experimental data. The …

Steel–concrete composite columns are used extensively in modern buildings. Extensive
research on composite columns in which structural steel section are encased in concrete …

A series of tests on concrete-filled SHS (Square Hollow Section) stub columns (twenty),
columns (eight) and beam-columns (twenty one) were carried out. The main parameters …

Concrete-filled steel tubular (CFST) columns are adopted in many structural applications,
especially for tall buildings, bridges and large infrastructure due to their substantial structural …

This study investigates the axial load behavior of concrete-filled steel tubular (CFT) columns
with the width-to-thickness ratios between 40 and 150, and proposes an effective stiffening …

The behavior of stub columns of concrete-filled rectangular hollow sections (RHS) subjected
to axial load was investigated experimentally. A total of 24 specimens were studied. The …

A method is presented to predict the complete stress–strain curve of concrete subjected to
triaxial compressive stresses caused by axial load plus lateral pressure due to the …
