Question

Which of the following factor is considered for classification of cross section?

(a) location where member is used

(b) width-to-thickness ratio

(c) length of member

(d) seismic force

This question was posed to me in an international level competition.

The question is from Cross Sectional Classification in chapter Plastic and Local Buckling Behaviour of Steel of Design of Steel Structures

Answer 1

The correct answer is (b) width-to-thickness ratio

The best I can explain: Cross section are classified into four behavioural groups depending upon  the material yield strength, width-to-thickness ratio of individual components (e.g. webs and flanges) within the cross section, and the loading arrangement.
