The parts prone to lightning strikes in buildings are the key protection aspects in lightning protection projects. In order to ensure the quality of lightning protection engineering, comprehensive site investigation and rigorous design and demonstration should be carried out in the early stage of the project, especially for the key protection of the parts of the building that are prone to lightning strikes. So where are the parts of the building susceptible to lightning strikes?
First, for flat houses or roofs with slopes no greater than 1/10, eaves angles, parapets, and eaves should be the parts prone to lightning strikes.
Second, for roofs with slopes no greater than 1/10 and less than 1/2, the corners, ridges, eaves angles, and eaves should be the parts prone to lightning strikes.
Third, for roofs with a slope of not less than 1/2, the corners, ridges, and eaves angles should be the parts that are vulnerable to lightning strikes.
Fourthly, in the case that the roof ridge has a flashover zone, when the eaves are within the protection range of the roof ridge flashover zone, there is no need for a flashover zone on the eaves.
The parts prone to lightning strikes in these buildings are the parts to be protected in lightning protection.
