Key words: seismic isolation, oscillation period, load relief, oscillation decrement, results processing

The results of studies of the dynamic characteristics of a three-storey fragment of a frame building made according to the SBK-SCF system "Prefabricated frigless frame with seismic-insulating kinematic foundations" are presented. Magnetic dampers are used at the support level.The building fragment was tested by loading the system with a horizontal static load using a stationary winch with subsequent load relief. It is established that the value of the oscillation period varies within 1.8-2.1 seconds depending on the amplitude of the impact.
