SEISMIC DESIGN METHOD TO CONSIDER “ANTI-CATASTROPHE” CONCEPT — A STUDY FOR THE DRAFT OF DESIGN —

Abstract

 It is requested to implement the concept of ”anti-catastrophie” property in the seismic design codes. It is not, however, a straight forward task because ”anti-catastrophe” concept has various significant differences from existing design codes. This paper identifies problems of the development of ”anti-catastrophe”- oriented seismic design codes, and proposed a new concept of ”category 2.” A framework of design code with ”category 2” is also presented. We also discussed conditions required for the society and government to make such new design codes effective, based on theoretical framework of risk governance and proposed several practical policies.
