Seismic Sustainability Assessment of Lavasan City

Earthquake is a natural and inevitable phenomenon which can cause huge losses of life and economy. Due to locating on seismic belt and its seismic condition, Iran country, is very sensitive to earthquake. The aim of this study was seismic sustainability of Lavasan city, to evaluate the seismic vulnerability of buildings based on the HAZUS method and geographical information system (GIS). Some information such as type of structures, number and size of floors, population of each regions, soil types and etc were gathered and used the risk analysis software SELENA for calculating. In this method the response curve gained from soil type based on IBC-2006 standard and damping effect for all kinds of structures with the methods listed is calculated in Fema-440. This output includes infrastructure damaged by the type of structure,  probable  loss  of  life  and  damage  to  property,  inflicted  by  the  design  based  on  Iranian  Code  of Practicefor Seismic Resistant Design of Buildings. The old area of Lavasan city, including areas 6, 9, 10, 11 and 12, shows the highest ratio of damages
