地盤連成を考慮した建築構造物の震害ポテンシャル

Abstract

The concepts of macro- and micro-zoning and earthquake damage potential are definedin the first part of this paper. Secondly, a practical method of the earthquake response analysisis presented applicable to the analysis of damage potentials for coupled soil and building structures.The method considering the elasto-plastic characteristics of both sub-soils and structures is basedon the modal analysis, use of response spectrum and linearization and iteration techniques. Thedistributions of damage potentials are completed in combination of the types of earthquakes, soilgrounds and structures. The illustrative examples for the typical structures constructed in theOsaka area are finally calculated and discussed.
