Abstract

Background: The main objective is to investigate the behaviour of cold-formed steel single and double angles subjected to tension. Methods: Sixteen single plain and lipped angle specimens and thirty two numbers of double angle specimens connected to the same side and opposite side of the gusset plate were tested in a Universal Testing Machine using ordinary black bolts of 10mm diameter. The experimental loads are compared with ultimate load calculated using BS 5950(Part V)- 1998, and AS/NZS 4600:2005. Results: Most of the single and double angles failed by net section fracture failure and the outstanding leg are subjected to local bend due to shear lag effect. Application: Angles are used in a variety of structures such as trusses, transmission towers etc. as tension members. Angles may be used as single angles or double angles and the connection may be bolted or welded.
