概要

This paper proposes new static seismic design methodology with newly defined DSC derived from elastic-plastic time historical seismic response analysis of components and allowable ductility factor to prevent damage to components. The process of the seismic response analysis to obtain the ductility factor considering load-deflection characteristic of components and definition of the allowable ductility factor based on the actual experiences are also described. Furthermore, trial analysis of the DSC for actual nuclear facility of KashiwazaNi-Kariwa Nuclear Power Station is conducted. It is expected that the new method will help diversify the existing seismic design system, which is based on equivalent elastic design, as well as increase the reliability of seismic design to deal with the uncertainty of the seismic motion.
