THE ACCOUNT OF PRIMARY NONLINEARITY OF THE GROUND DURING A SEISMIC EFFECT ON A PUMP STATION
The primary nonlinearity of the ground in the event of a seismic effect of the earthquake level on the incorporated pump station of the Rostov NPP unit 3 is accounted for. The equivalent linear method is used where one-dimensional iterative analysis of the wave propagation is done. The direct and inverse Fourier transforms for a temporary variable are used. The result of the work is the acceleration time history on the foundation level which sets the seismic impact on the pump station.
