Seismic Stability of Equipment on a Single Support, Partly Embedded in the Soil

The report considers the problems of theoretical and experimental analysis of seismic response of equipment placed on a reinforced concrete or steel support. Calculations had been accomplished on the basis of FEM. The procedure made it possible to determine the influence of dimensions of ground area which surrounded the support, soil properties and non-stationary nature of seismic input on the parameters of forced vibrations in the zone of equipment attachment. It is shown, that the amplitude of action on the equipment can considerably exceed the amplitude of seismic ground motions. On the basis of the data received the requirements on the test platform during the full-scale testing of «soil-support-equipment» system had been formulated. Practical realization of these requirements on the seismic platform USP-300 allowed in gross volume to inspect the seismic stability of a standard support on the basis of reinforced concrete strut SB115 7 under conditions of reproducing a non-stationary broadband seismic input of the magnitude 9 earthquake. The testing results had confirmed correctness of the design predicted evaluations.
