This sign seems to have an interesting physical design. The holes may be there to reduce wind loads in a hurricane-prone environment.
Some municipalities legally require the addition of ‘wind vents’ for large signage.
A group of researchers set out to test the efficacy of such wind vents – and challenge the thinking behind those laws.
The key takeaways:
- The wind-loads varied depending on if it was a solid or ‘bilowing’ type sign. The original thinking (and subsequent legislation) seems to have mostly stemmed from science related to non-solid structures.
- A “swiss-cheese” type design might actually significantly reduce wind loads.
No wait they’re bullet holes:
