Determination of Road Functionality for Küçükçekmece District Following a Scenario Earthquake for Istanbul

Istanbul has been affected by earthquakes throughout its history. The most recent earthquake to shake Istanbul was on August 17 1999, along the North Anatolian Fault, 12 km southeast of the Izmit Province, with a magnitude of 7.4. Following the 1999 Izmit earthquake, the earthquake risk in Istanbul started to draw attention and many scientific studies were conducted on the potential earthquake risk in this city. Based on these studies, predictions are that Istanbul is going to face a major earthquake in the near future and this will cause severe damage to the built environment. It is estimated that the damage caused by the anticipated earthquake will be extensive as a consequence of Istanbul’s low quality building stock of Istanbul. The buildings that have the possibility of being damaged cause debris around them. If roadside buildings collapsed during the earthquake, the scattered parts of the buildings could cause roads to lose their functionality. Not only building damage but also transportation damage analysis is necessary to use risk mitigation studies and decisions, being that experiences showed that the functionality of transportation structure effects post-earthquake emergency response and recovery operation seriously. This study aims to reveal a method for road functionality in Küçükçekçekmece following a potential Istanbul Earthquake by using building collapse direction and bridge damage.
