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

A)
seismic force
B)
length of member
C)
width-to-thickness ratio
D)
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?
A)
residual stress
B)
seismic load
C)
initial lack of straightness
D)
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.
