| Research Abstract |
In this study, acceptable limits of seismic economic loss for buildings were formulated from the viewpoint of profitability. The limit is considered to be used as a design target for seismic design methods. If repair costs exceed the limit, the building will lose profitability and fail economically. The acceptable limits of 1193 J-REIT buildings were calculated and the influence of their total floor area and economic situation was analyzed. Contrary to the expectation, the analysis revealed that the acceptable limit of the buildings with large total floor area and better economic situation tends to be smaller, which means buildings having significant role in economic activity tend to be vulnerable to seismic economic losses.
