What is Experimental Direct Lightning Current Distribution in a Reinforced Concrete Building about?

When a building is hit by a direct lightning strike, the communication equipment may be damaged due to the current flowing on the columns, girders, and walls. Therefore, it is necessary to determine the current distribution and establish preventive procedures. Previously, the linear model in which the columns and girders are expressed in terms of lumped elements has been used for estimation of the current distributions in the buildings. However, few buildings have been studied. It is very important to understand correspondence between the models and the actual structures, such as the treatment of the buildings walls and floors. The researchers in the past have experimentally investigated the equivalent impedance of the columns and girders with complex shapes and measured the currents on the actual columns and girders by designing a large-diameter Rogowski coil. Based on these results, a lightning current application experiment was carried out using a steel-reinforced concrete building and a model scale without walls and floors. The effects of the ground, walls, and floors were studied and a comparison was carried out with the conventional computational method using the linear model
