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.
