Abstract

Construction of existing structures, such as masonry or concrete buildings, often pre-date the introduction of modern seismic codes. The quality of the construction in these types of buildings is often poor or the techniques used in the construction are now known to be unacceptable in a seismic event. In some combinations of circumstances, such as Tangshan in China, and Spitak in Armenia, this can lead to tragic loss of life and a significant expense to the world community. This loss is due to the application of an extreme environmental load, such as a seismic event. The current dilemmas in the intraplate regions of the world relate to the strategy that should be used to prepare for earthquakes. The strategy that is developed for an area must consider the funds that should be expended on retrofitting the stock of existing buildings. Then after an earthquake determining what is economic to repair and what should be demolished. Finally, how should the funds be expended to the greatest benefit of the population? The purpose of this paper is to suggest a simple model for estimating fatalities in major earthquakes based on the data collated mainly for the twentieth century. This model, which is developed for masonry study purposes, can be used to estimate the potential fatalities under a standard set of conditions. This model can then be used in the development of rehabilitation and repair strategies that provide the greatest economic and social benefit to the community.
