Civil Engineering QUESTION #6615
Question 1
In AISC LRFD, the resistance factor $\phi$ for 'Tension Yielding' on the gross section is:
  • 0.75
  • 0.85
  • 0.9✔️
  • 1
Correct Answer Explanation
Tension yielding is a ductile failure mode, so $\phi = 0.90$ is used. Tension fracture (at holes) is more critical and uses $\phi = 0.75$.
