In this study, the seismic impact between two adjacent structures with different lateral stiffness is investigated through a computational model. The method used for the impact analysis in this study is based on the Hertz contact law combined with a non-linear damper...

The seismic SSSI effects in the nuclear island buildings for a representative plant are considered. The nuclear island consists of four buildings. The seismic SSSI effects on the lightest and smallest building (building of interest) are analyzed with two different...

In the nuclear power industry large pile groups are used world-wide at soil sites with soft and weak near-surface soil layers as foundations for both safety and non-safety related structures. Entire nuclear power plant (NPP) facilities are founded on piles in areas of...

This paper introduces a new alternative for soil-pile-structure interaction analysis, based on established soil-pile interaction theory, which accommodates a wide range of foundation conditions. A description of the theoretical formulation and its implementation into...

The benefits of seismically isolating nuclear power plant buildings, in terms of reducing seismic risk, are well established but the possible impacts on overnight capital cost are unknown. Projects funded by EPRI and ARPA-E are now underway to characterize possible...
