Question

Which of the following is true?

(a) in case of rolled section, less thickness of plate is adopted to prevent local buckling

(b) for built-up section and cold formed section, longitudinal stiffeners are not provided to reduce width to smaller sizes

(c) local buckling cannot be prevented by limiting width-thickness ratio

(d) in case of rolled section, high thickness of plate is adopted to prevent local buckling

I had been asked this question in an internship interview.

I'm obligated to ask this question of Beam Types and Sections topic in portion Design of Beams of Design of Steel Structures

Answer 1

The correct option is (d) in case of rolled section, high thickness of plate is adopted to prevent local buckling

For explanation: In case of rolled section, higher thickness of plate is adopted to prevent local buckling. Local buckling cannot be prevented by limiting width-thickness ratio. For built-up section and cold formed section, longitudinal stiffeners are provided to reduce width to smaller sizes.
