When a direct strike occurs, the lightning surge current will intrude into the steel frame and steel bar of the building, forming a high lightning electromagnetic environment inside the building, which will affect the telecommunications equipment set in the building. Therefore, the problem of lightning protection in buildings becomes more and more important. In this paper, by studying the distribution law of lightning electromagnetic field in buildings, the intensity of magnetic field generated in buildings under different lightning strikes is analyzed. According to the three-dimensional diagram and equivalent diagram of the intensity of lightning magnetic field in each case, when the building encounters direct lightning, the lightning electromagnetic field is the strongest near the leadoff line, and the middle zone is weak. The lightning protection measures inside the building are put forward.
