Stocked Size Range and Shapes. Square:0.500" to 16.000" with 0.065" to 0.625" Wall Thickness. Rectangle:1.000" x 0.500" to 20.000" x 12.000" with 0.065" to 0.625" Wall Thickness. Round:0.750" to 20.000" O.D. with 0.065" to 0.625" Wall Thickness. Eccentric Compression Strength of Rectangular Concrete May 05, 2017 · An experimental study was performed to investigate the structural behavior of thin-walled rectangular concrete-filled tubular (RCFT) columns. This study mainly focused on the effects of a high-strength steel slender section on the overall eccentric compression capacity.

Experimental study and numerical analysis on seismic

May 01, 2021 · Du et al., has conducted experimental and theoretical studies on rectangular CFT made of high-strength steel, although the CFT columns could make full use of high-strength steel by restraining its buckling inward, the problems caused by outward buckling remain to be solved. And the application of FRP may help solve these problems. High strength steel square and rectangular tubular stub This paper presents the experimental and numerical investigations of high strength steel square and rectangular tubular stub columns infilled with concrete. Firstly, a series of tests was conducted on cold-formed high strength steel (CFHSS) square and rectangular tubular sections infilled with three different concrete compressive strengths, i.e., 40, 80 and 120 MPa. High-Strength Rectangular CFT Members:Database, May 05, 2018 · The benchmarked models are then used to perform comprehensive parametric studies to (1) address gaps in the database and (2) develop effective stress-strain relationships for modeling the steel tube and concrete infill of high-strength rectangular CFT members, while indirectly accounting for the effects of confinement, yielding, and local buckling.

Rectangular double-tube concrete columns with an internal

Aug 01, 2020 · The post-yield strength of the high strength steel can be effectively utilized in rectangular DTCCs. The axial load-axial strain curves of rectangular DTCCs feature approximately bilinear behavior. The inner steel tube offers additional lateral confinement to core concrete so that the majority of the concrete in a DTCC is effectively confined by the steel tube and the FRP tube.

Strenx Tube 700MLH - High-strength steel tubing - SSAB

Its high strength combined with naturally stiff form of welded hollow section enables construction of stronger and lighter structures. Strenx® Tube 700MLH meets or exceeds the requirements of EN 10219-3 (2020) and it is CE marked according to EN 1090-2. Typical applications include load-bearing structures in the lifting, handling and transportation segments, especially in conditions that require extremely good toughness. Strenx® Tube 700MLH is available in circular, square and rectangular Structural hollow sections - SSAB - SSAB high-strength steelSSAB manufactures cold formed and welded hollow steel sections, which according to EN 1993 (Eurocode 3) fall into buckling curve c (curve a or b in concrete filled columns). The buckling behavior of steel columns leads to situations where utilizing high strength steels is difficult especially with longer and slender columns.
