Assessment and Planning for Urban Vulnerability against Earthquake

ABSTRACT: Iran is located in a seismic region; many earthquakes on different area have been recorded through thousands of years. Based on seismic macrozonation hazard map of Iran, Tehran is located in very high level of relative seismic hazard zone. Experiences of recent earthquakes in Bam, Manjil-Rudbar and other major earthquakes shows existing buildings and other constructions have not enough bearing capacity to resist earthquake loads. In addition, exponential growth in population and irregular expansion in urban area especially in Tehran make it highly vulnerable. In this thesis one of vulnerable urban area in north of Tehran is typically selected and by using effective and applicable vulnerability parameters tried to find a proper approach for categorization of the area based on the risk of vulnerability. Similar examples of seismic rehabilitation in Iran, Italy, Japan and United States of America are reviewed to find an appropriate solution in case of earthquake happening . Finally some general and specified applicable recommendations are presented as a proposed rehabilitation approach.
