In the last fifteen years, Turkey has lost tens of thousands of its citizens and huge amounts of economic properties in moderate and severe earthquakes. Moreover, most of the population and industry of Turkey is under the threat of a possible major earthquake since they are located in earthquake prone regions. The current seismic code of Turkey [1] was rewritten in 1998 to enable the satisfactory performance of the structures and thus to reduce loss after a major earthquake. However, a vast majority of the structures in Turkey had been constructed before the adaptation of the 1998 Turkish Earthquake Code [1]. Moreover, newstructures are not generally designed and/or constructed according to the provisions of this code resulting in a huge number of deficient structures. As a result the engineers in Turkey, like most of their colleagues in the world, are faced with a critical question which must be answered immediately: Which buildings are safe and which must be strengthened or even demolished? For decades researchers have been studying on developing seismic vulnerability assessment procedures to overcome this problem. These vulnerability assessment procedures can be categorized in three according to the level of complexity they contain. The first level of seismic assessment procedures is known as the walk-down survey or street survey and is the quickest and simplest way of ranking the buildings in a building stock relative to each other based on their certain attributes. The typical parameters used in this type of assessment procedures are the number of stories, the age of the building, vertical
