摘要: Abstract: This paper presents the results of new tests conducted on built-up cold-formed steel section battened columns. The pin-ended columns were axially loaded and consisted two channels placed back-to-back at different center-to-center distances. had geometries slenderness ratios. column strengths, load-axial shortening, deformed shapes failure, failure modes, load-lateral displacement strain relationships measured observed in tests. In overall, experimental investigation aimed to provide sufficient test data for finite element models be developed compensate lack this form construction. have shown that offer a considerable increase strength compared with single provided correct ratios considered. It was also effect modes load-displacement relationships. strengths design calculated using current codes practice, detailed discussions conclusions.
