title = "Behaviour of cold-formed high strength steel tubular X-joints with circular braces and rectangular chords",
abstract = "This paper presents a test program to investigate the static strengths of cold-formed high strength steel X-joints made of circular hollow section braces and square as well as rectangular hollow sections chords. In total, 10 X-joints were tested under compression. The nominal yield strengths of tubular members were 900 and 960 MPa. The welding was performed using semi-automatic gas metal arc welding process. The measured value of brace-to-chord width ratio (β) ranged from 0.59 to 0.89 and chord width-to-thickness ratio (2γ) ranged from 20.5 to 30.5. Two failure modes were observed, namely chord face failure (F) and a combination of chord face and chord side wall failure modes (F+S). The static strengths obtained from tests were compared with nominal strengths predicted from Eurocode 3 and CIDECT. For the range of tests undertaken, it has been demonstrated that the current design rules in these specifications are quite conservative and inaccurate.",
