The aim of this work is to test a multi-modal nonlinear static method for seismic impact of the "controlling earthquake" level for high-rise structures on the example of a wind power plant (WWP) with a capacity of 1.5-2.0 mW of the Adyghe WPP using computer modeling in the LIRA 10.10 PC. Additionally, the results were verified in the PC “Ansys”. The main bearing element of the WWP is a tower-pipe with a weak taper, the material of which is high-strength steel S355. The assessment of the structure seismic resistance is performed in physically and geometrically nonlinear settings. At the same time, the Vaughn-Mises strength theory was used for steel. Comparison of the calculation results proves the effectiveness of the multi-modal nonlinear static method. The method under consideration has a number of advantages: tolerance to the initial data in terms of numerical description of the seismic impact, less machine capacity of the calculation in comparison with the direct dynamic method, and the ability to automate the calculation process fully.
