Q: Which of the following is not a service ability criteria?
  • A. Deflection
  • B. Fatigue
  • C. Vibration
  • D. Force resistance
Correct Answer: Option D - Serviceability limit state– It include vibration, durability, deflection and deformation and repairable damage due to fatigue cracking etc. Limit state of collapse– It include flexural, compression shear, torsion, turning, sliding, buckling and fracture due to fatigue. • Durability of member is ensured by cover requirements grade of material etc.
