| Abstract: | The CAD graphing method is introduced by the paper to calculate the equivalent area of intercepting the same number of lightning by buildings to make the calculation results of expected annual number of lightning more reasonable and closer to lightning protection requirements of actual projects, considering the higher calculation values of expected annual number of lightning in degign of protection against lightening and combining the actual engineering project. |
| Keywords: | design of protection against lightning expected annual number of lightning equivalent area correction coefficient annual average ground flash density average annual thunderstorm days lightning protection classification of buildings CAD graphing method |
