Which of the following is advantage of HSFG bolts over bearing type bolts?

Civil Engineering : Steel Structure Design - Quiz(MCQ)

high strength fatigue

low static strength

joints are not rigid

bolts are subjected to shearing and bearing stresses

Correct Answer : high strength fatigue

Explanation : The advantages of HSFG bolts over bearing type bolts are :

* joints are rigid
* bolts are not subjected to shearing and bearing stresses as load transfer is mainly due to friction
* high static strength due to high frictional resistance
* high strength fatigue since nuts are prevented from loosening
* smaller number of bolts results into smaller number of gusset plates.

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.
