| Summary: | Lightning strikes affect the building structures by producing high electric field on the surface and around the building structrure. Lighnting air terminal is a traditional enemy of the thunder storm as it captures the lightning flashes. Effect of lightning flash on the building structrue when the lightning air terminal was not installed and when it was installed on different building structure was studied in this paper. When thunder storm strikes a building the electric field effect is propagated throughout the building surface and it damages the entire building.When the air terminal is places on the corners/edges it capture the lightning flashes on certain points and discharge it into the ground and the building remains safe. This phenomenon was studied in detail in this paper and it was proved that by installing the air terminal the remaining building structrue was safe and the electric field instensity was concentrated on the installed air terminal rather than the whole roof top and the rest of the building |
