| Summary: | Human progress on prediction of the time and place of release the energy and movement of the inner layers of the earth for prevent of the disaster can be cuased by an earthquake, has been very little. So now the only practical way to deal with this natural phenomenon is the pridicting of damages and then equipping and preparing to reduce the losses and casualties of it. Generally, the purpose of this study was to assess the seismic losses of structures in Hamedan to estimate the vulnerability in order to increase safety and improve conditions .This study, using informations gathered by the Statistics and Information Technology Organization of Hamedan Municipality -like type of structures, number and size of floors, population of each regions, soil types and etc.- and is implemented with the HAZUS method and the risk analysis software ''SELENA ver 6.0". In this method, for calculating the seismic performance of structures, the demand curve of various structures with different damping effects and the response curve based on soil type are crossed together.The outputs of this research include damaged area by the type of structures, probable loss of life and damage to property inflicted by the design earthquake of Iranian Seismic Code (Standard 2800). The results of the analysis indicate that the prediction of the average damage ratio of Hamedan in areas 1, 2, 3 and 4 is 17.9, 16.1, 19.8, 14.4 percent, respectively, and the average damage ratio is 18 percent. GIS 10.2 was used for illustrate the results. |
