Q: Which of the following is considered as Ultimate (safety) limit state in limit state design of steel structures?
  • A. Vibrations in structure causing discomfort
  • B. Corrosion and durability
  • C. Repairable damage due to deflection
  • D. Fracture due to Fatigue
Correct Answer: Option D - Ultimate limit state design of steel structures considered are– • Fracture due to fatigue. • Stability against overturning and sway • Brittle fracture • Strength (including general yielding, rupture, buckling and transformation into a mechanical). When the ultimate limit states are excepted, the whole structure or part of it collapses. ⇒ Serviceability limit states considered are • Deflection • Vibration (for example, wind-induced oscillation) • Repairable damage due to fatigue • Corrosion and durability.
