Experimental and numerical analysis of the seismic safety of technology support structures in NPP

This paper gives the methodology to get the floor response spectra of the buildings following the results of the probabilistic assessment. On the base of the geophysical and seismological monitoring of locality the peak ground acceleration and the uniform hazard spectrum of the acceleration was defined for the return period 10 000 years. The methodology of the seismic resistance of the cable support structures are presented. The experimental and numerical analysis of the seismic resistance of the technology structures are discussed.
