Behaviour of Cold Formed Steel Starred Section Subjected to Axial and Eccentric Load Condition


  • Department of Civil Engineering, Chennai, Tamil Nadu, India


Objectives: This paper presents the ultimate load carrying capacity and behaviour of Cold Formed Steel (CFS) starred section with different end conditions and the specimens are subjected to axial compression. Methods: Theoretical study is carried out by using Euler’s load equation. Six plain sections of different sizes of 2mm thickness were tested as short columns. The analytical study is carried out using FEM software. The specimen used for testing have different dimensions, 60×60×2mm and 50×50×2mm with welded end condition, balled end condition and bolted end condition. The specimens are also tested experimentally by applying axial compression loading. Findings: The analysis is numerically carried out using FEM software and the results are compared. The experimental investigation of the cold-formed steel column is carried out by testing the column under loading frame with load applied manually and the test results are found match with the theoretical values. Compression tests were carried out on cold-formed steel starred angles under different end connections. As a result, welded end condition provides more strength than balled end condition where balled end condition provides more strength than the bolted end condition. Applications: This results can be further used with different section size or with different end condition under different loading conditions to find the ultimate strength of cold formed steel.
