    Abstract. Foundation slabs of finite sizes are widely used in industrial construction. Quite a variety of industrial equipment is installed on such structures. There is a need for a more detailed consideration and clarification of methods for calculating such structures. The possibility of equipment installation on separate plates or directly on the floors makes it possible to get significant savings in materials and increases the universality of industrial buildings. The article presents recommendations for the calculation of foundation slabs for dynamic loads from industrial equipment. An example of calculating a free-standing foundation plate for an inertial heavy-type screen is given. The calculations were performed by the finite element method. The solution of differential equations of motion of a system with a finite number of degrees of freedom is constructed in the form of an expansion according to the forms of natural oscillations of the system. The calculation of the loads from the screen, the sequence of selection of optimal vibration isolators are given. The main dependencies for the calculation of such systems in transient modes are given. The parameters of the design scheme and the features of the application of loads are described in detail. Based on the existing recommendations and the above methods, a set of programs has been implemented in the high-level python programming language, calculations in which allow taking into account the features of equipment operation in transient and stationary modes, vibration isolation, as well as various types of dynamic loads. The presented material makes it possible to perform calculations of such structures with a sufficient degree of accuracy. The results of calculations show that it is possible to install heavy-type equipment on separate slabs, taking into account the restrictions given in the article, and, as a result, on the rigid underlying layers of the floors of industrial buildings.
    Key words: foundation plate, industrial equipment, dynamic loads, active vibration isolation, finite element method, method of decomposition by eigenforms of vibrations.
