Review
This paper deals with the verification of the general assumption used in dynamic analysis of equipment under a seismic excitation — assumption about uncorrelated components of in-structure response accelerations (RA). With the help of examples of seismic dynamic analyses of two reactor buildings (VVER-1000) the violation of such assumption is demonstrated. The reasons for appearance of RA components’ correlation and importance of this effect are discussed.
