Identify the INCORRECT statement with respect to the type of buckling of steel columns,
1
The flexural buckling is also called as Euler buckling when the plastic behaviour of column occurs.
2
Compression members with any type of cross-sectional configuration can undergo flexural buckling.
3
Flexural torsional buckling can occur only with unsymmetrical cross-sections.
4
Torsional buckling is caused by twisting about the longitudinal axis of the member.
