概要

This paper proposes new static seismic design methodology with newly defined DSC derived from elastic-plastic time historical seismic response analysis of the 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, definition of the allowable ductility factor based on the actual experiences and the activities for a decision of Guidelines for Seismic Design with Static Seismic Coefficient considering Ductility Factor are also described. It is expected that the new method will be improved within present management system for the Nuclear Power Station, 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.
