The article describes dynamic analyses of frame foundation for a turbine set with a capacity of 20 MW. In the introduction, the author discusses a general method of performing dynamic calculations in building structures. The natural analyses were performed using three methods: a simplified method, a finite element method for the bar structure and the volumetric structure. The course of action was described in detail. The quality of the results was compared. General recommendations for this type of analyses were formulated.
