DEMONSTRATION OF NONLINEAR SEISMIC SOIL STRUCTURE INTERACTION AND APPLICABILITY TO NEW SYSTEM FRAGILITY CURVES SEISMIC
Risk calculations should focus on providing best estimate results, and associated insights, for evaluation and decision-making. Specifically, seismic probabilistic risk assessments (SPRAs) are intended to provide best estimates of the various combinations of structural and equipment failures that can lead to a seismic induced core damage event. However, in general this approach has been conservative, and potentially masks other important events (for instance, it wasn’t the seismic motions that caused the Fukushima core melt events, but the tsunami ingress into the facility).
