Civil Engineering QUESTION #6622
Question 1
When checking for 'Web Local Yielding' in a beam, the load is assumed to distribute from the outer surface of the flange at a slope of:
  • 1:01
  • 01:02.5
  • 1:05✔️
  • 2.5:1
Correct Answer Explanation
AISC assumes that a concentrated load applied to a flange spreads out at a 1:2.5 slope (1 horizontal for 2.5 vertical). Therefore, the length of the web resisting yielding at the toe of the fillet is $N + 5k$ (for interior loads).
