Behaviour of Cold-Formed Steel Built-Up Square Battened Columns Composed of Different Spacing of Chord and Battened Plate

Abstract

This study investigates square hollow sections (SHS) in built-up cold- formed steel (CFS) battened columns, aiming to assess structural performance and the impact of varied spacing configurations between chords and battened plates. Experimental testing involves compression tests to evaluate load-bearing capacity and deformation under axial loading, with deflection measurements assessing overall stiffness and reactivity. Findings enhance understanding of structural behavior, shedding light on load-bearing capability, deflection behavior, and stability traits under diverse spacing conditions. The study evaluates existing design recommendations for square hollow sections, providing valuable insights for optimized CFS battened column design and construction, benefiting engineers and professionals in maximizing structural performance.
