Abstract
This study is an attempt at incorporating considerations of economic impact into Seismic Design Decision Analysis. The economic impact losses considered here are those that result from the loss of income in a region resulting from damage to buildings and structures induced by earthquakes. This paper has focussed primarily upon illustrating the methodology of incorporating economic impact into Seismic Design Decision Analysis. An analytical basis of obtaining economic impact probability matrices has been established. Economic impact loss estimates for several locations and different seismic risk considerations have been obtained. And, finally, the efficacy of anti-seismic design strategies for Boston, San Francisco, and the Puget Sound area have been evaluated by combining building damage and economic impact losses in the benefit-cost analysis, and tentative conclusions regarding design strategies have been indicated for these locations.
