Discussion
Consider the following statements about cut-outs in shear webs:
1. A flanged hole lets the shear divert smoothly around the opening.
2. The flange also stabilises the surrounding web against buckling.
3. Plain square holes are preferred at high-shear stations.
Which of the statements given above is or are correct?
Answer: A
Correct answer: 1 and 2 only
Statements 1 and 2 are the reason flanged holes are used: the flange gives the diverted shear a stiff path round the opening and stabilises the free edge against buckling. Statement 3 is the opposite of practice - a plain square hole puts sharp re-entrant corners into a highly stressed web, which is where fatigue cracks start.
