| Sumario: | Earthquake is a Natural phenomenon that human knowledge, despite achieveing much information about the origin and mechanism of it; So, it is essential that the logical and statistical manner and in accordance with existing to forecast potential losses and damages caused by the earthquake and identifying shortcomings in the systems and urban structures And resolve them before the disaster measures applied. In general, the aim of this study was to assess the seismic vulnerability of buildings in Mashhad in order to understand the current state of existing buildings in the city that can be vulnerability them in order to increase safety and improve existing estimates. This study, using informations gathered by the Statistics and Information Technology Organization of Mashhad Municipality -like type of structures, number and size of floors, population of each regions, soil types and etc.- and is implemented with with ''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 include damaged area by the type of structures, probable loss of life and damage to property, inflicted by the design earthquake of Iran 2800 code. GIS 10.2 was used for illustrate the results. From these results it can be understood the 4, 2, 5, 6 regions of Mashhad due to greater vulnerability, requires retrofitting and needs more attention. |
