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

Civil Engineering : Steel Structure Design - Quiz(MCQ)

seismic force

length of member

width-to-thickness ratio

location where member is used

Correct Answer : width-to-thickness ratio

Explanation : 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.

Which of the following is not a parameter for decrease in strength of slender member?

residual stress

seismic load

initial lack of straightness

variation of material properties

Correct Answer : Option (B) : seismic load

Explanation : The decrease in strength of slender member is due to following parameter : imperfections- initial lack of straightness, accidental eccentricities of loading, residual stress, and variation of material properties over the cross section.
