Steps in the calculation of massive (particularly, columnar) foundations under vibroactive equipment with a horizontally-directed disturbing force are analyzed. An estimation of the soil reactions under the horizontal displacement of the foundation top is made, and the equations of horizontal-rotational vibrations of the object are solved. The calculation method uses transfer and impulse transition functions of linear systems with a finite number of degrees of freedom. An example of the calculation and a brief analysis of the results are given.
