Abstract


Due to locating on seismic belt and its seismic condition, Iran country, is very sensitive to earthquake. Because of estimating importance of damages and casualties through earthquake, many countries have selected different methods for seismic hazard analysis. Many of these methods are based on earthquake severity. Although damage function majority of these methods is based on seismic data, structural parameters are not considered. The objective of current study is to evaluate the seismic vulnerability buildings in Qom city based on the hazus method and geographical information system (GIS) and level of damage and victims is calculated for different kinds of structures, separately, in the whole region of investigation. The open source software SELENA is applied to perform probabilistic loss estimates. Due to the lack of studies providing required information from structural point of view in our country, and the existence of similarity between structural codes of Iran and that of United States, HAZUS-MH (Hazard Us – Multi Hazard Loss) structures coefficients are used. The results indicated provides if an earthquake based on standard 2800 occurs, the number of casualties would be 25000 persons and economic losses are 1078660213$.
