“…Because of that, the strength calculations of loaded elements of energy facilities and industrial buildings and structures in combination of loads don't take into consideration the impact of a thunder's shock wave. There are separate works [1][2][3][4][5][6][7][8][9] in which the features of the shock wave formation during a lightning strike are studied. Considering the variety in the designs of elements of buildings and facilities, numerical 3d models of elastic cantilever beams were used to study the shock wave.…”

The paper considers the issues of strength of energy facilities’ load-bearing metal structures under the influence of acoustic waves produced by a lightning strike. The studies were carried out using finite element test models of cantilever beams of various designs. The beams are loaded with the total load of the beams’ own weight and the shock wave produced by a lightning strike from a distance of 1 m from the beams’ surface. Calculation results substantiate the necessity to consider the impact of thunder when calculating the structure of energy facilities made of sheet metal. It was revealed that deformations and loads in sheet metal structural elements at the time of a lightning strike from a distance of less than 1 m from the structure’s surface may exceed the acceptable values for the yield strength of structural steels. As a result of the work, recommendations were made on the location of the lightning rods and the need to reduce the operational loads during a thunderstorm.
