Structural elements made of seam-welded hollow sections are considerably less expensive than their seamless equivalents. This is a strong incentive for their use, but the current steel design standards still contain recommendations for seam-welded hollow sections based on test results performed with sections produced using outdated steel grades and fabrication processes. These design procedures are even more conservative when applied to composite tubular seam-welded elements. This paper presents an experimental campaign performed to investigate the structural behaviour of steel-and concrete-filled composite columns made with seam-welded rectangular hollow profiles. The experiments involved columns with only steel sections, concrete-filled and concrete-filled plus additional reinforcing bars. The main aim of the tests was to identify the contribution of each component in the overall structural response. The results enable an evaluation of the design recommendations present in Eurocode 4 aiming to determine less conservative buckling curves to be used for the investigated composite columns made of seam-welded rectangular hollow sections.

ABSTRACT:The contribution of CFRP (carbon fiber-reinforced polymer) to concrete-filled square steel tube (CFSST) is considered in this paper. Based on the experimental study of six high strength concrete-filled square steel tubular stub columns with inner CFRP circular tube (HCFSST-CFRP), the finite element software ABAQUS is employed to analyze the mechanical behaviors of HCFSST-CFRP stub column under axial compression load. Mechanism of interactions among steel tube, concrete core (includes two parts: innermost concrete and sandwich concrete) and CFRP is analyzed, and a simplified equation of loads shared by innermost concrete and sandwich concrete is given by regression analysis. Longitudinal stress distribution in the concrete section, load shared coefficient and axial load-strain relationships are presented. The confinement effect of the CFRP tube increases ductility of HCFSST stub columns remarkably. Innermost concrete suffers most of axial load after specimen reaching ultimate bearing capacity because of the confinement effect of CFRP tube. CFRP tube begins to work obviously at the descent stage after stub column reached ultimate bearing capacity.
