Flexural buckling behaviour of 690 MPa high strength steel H-section columns
•A series of parametric study was carried out to investigate effect of geometry and imperfections on column strength.•α and χ are positively correlated: χ increases at different rates as α increases.•χ decreases with the increase of β at very low rate and the effect of β on χ is not very obvious.•Re...
