Which of the following is true regarding plastic design methods?

Civil Engineering : Steel Structure Design - Quiz(MCQ)

difficult to design for fatigue

more saving in column design

moments produced by different loading conditions can be added together

lateral bracing requirements are less stringent than for elastic design

Correct Answer : difficult to design for fatigue

Explanation : * There is little saving in column design
* lateral bracing requirements are more stringent than for elastic design
* difficult to design for fatigue
* moments produced by different loading conditions needs to be calculated separately(cannot be added together) and the largest plastic moment is selected.

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.
