Investigation into Seismic Performance of For-Profit Buildings in terms of Economics
For-profit buildings in cities such as commercial buildings for rent play a significant role in urban economic activities, and their failure would cause enormous economic loss. To reduce such losses in the event of a severe earthquake, it is necessary to clarify the damage limits of for-profit buildings in terms of business continuity.This paper investigates the seismic performance of for-profit buildings in terms of economics by introducing an economic damage index, and also discusses the following issues: 1) Permissible repair cost for buildings derived from property information such as construction cost, projected revenues and discount rate, and a resulting damage limit for failure in business continuity. 2) Upper-bound investment for earthquake resistance derived from a balance between the cost of earthquake resistance and its benefits, and resulting inevitable damage in terms of economics. 3) Vulnerability of urban for-profit buildings with low business risk to earthquakes, compared with suburban for-profit buildings with high business risk.
