What is gross section yielding?(a) considerable deformation of the member in longitudinal direction may take place before it fractures, making the structure unserviceable(b) considerable deformation of the member in longitudinal direction may take place before it fractures, making the structure serviceable(c) considerable deformation of the member in lateral direction may take place before it fractures, making the structure unserviceable(d) considerable deformation of the member in lateral direction may take place before it fractures, making the structure serviceableThe question was posed to me in an interview.I'd like to ask this question from Modes of Failure, Slenderness Ratio and displacement in section Design of Tension Members of Design of Steel Structures

Answer»

The correct option is (a) considerable deformation of the member in longitudinal direction MAY take place before it fractures, making the structure UNSERVICEABLE

Explanation: Tension member without bolt HOLES can resist LOADS up to ultimate load without failure. But such a member will deform in longitudinal direction considerably(10-15% of its ORIGINAL length)before fracture and the structure becomes unserviceable.
