Non-Liner Response Analysis of Nuclear Facilities Subject to Horizontal and Vertical Ground Motions

Abstract eng:
In this study, non-linear dynamic response analysis was carried out on a full-scale BWR building with the input direction and amplification factor of ground motion as parameters, and the effects of different combination of these parameters on horizontal response of the building were reviewed. As a result, it was found that the input of vertical ground motion had no significant effect when the building was in an elastic region, and that the input of vertical ground motion had effects on the distribution of the maximum horizontal response acceleration and the amplitude of the prevailing periodic band of horizontal floor response spectrum when the building reached a non-linear region.
