地盤増幅を考慮した一様ハザードスペクトルに基づく建築構造物の地震リスク評価手法

抄録

This paper proposes a new method of evaluating the uniform hazard response spectra on the ground surface and estimating the seismic risk of a building structure based on the eauivalent linearization method. The method is useful to examine the seismic risk management of a building structure, because it gives quantitatively the seismic risk of the building structure considering the seismic environment of the adjacent area, the amplification characteristics of the subsurface structure of the site and the restoring force characteristics of the building structure. Applying the method to a case study, it is found that in the seismic risk management of a building structure it is important to control the building parameters such as the yield shear coefficient according to the amplification characteristics of the subsurface structure.
