Research on Streamlining Seismic Safety Evaluation of Underground Reinforced Concrete Duct-Type Structures in Nuclear Power Stations: Part-1. Scope, Objectives and Major Results of the Research

摘要

In Japan an extensive review has been made on the earthquake safety evaluation of civil engineering structures since the Great Kobe Earthquake occurred in January 1995. Also, underground important reinforced concrete structures in nuclear power plants are critically scrutinized in line with the streamlining the seismic design. Electric power industry has been jointly conducting research project on this specific type of nuclear power related RC structures since 1987, dividing the research into two phases, the first from 1987 through 1991 and the second from 1997 through 2001. The paper introduces the historical background and the achievements of the research and the concept of seismic safety assessment guideline to be concluded within 2001. The paper serves as an introductory briefing on the series of papers, which follows as Part-2 through Part-6.
