PERFORMANCE ANALYSIS OF EARTHQUAKE RESISTANT BASED URBAN TRANSFORMATION PROJECTS

Abstract

Earthquakes have often produced economic and social disaster. The last destructive earthquake on west side of the NAFZ is 1999 İzmit (Mw = 7.4). On August 17, 1999, a major earthquake occurred in the Marmara region, western Turkey, with a magnitude Mw = 7.4. The total observable length of the rupture was about 100km. The number of condemned buildings after the earthquakes amounted 23,400. There were 18,373 accounted deaths. First reason of this damage is inadequate design and low construction quality of buildings without control and supervision. The second important result is wrong urbanization policies of local and central government. Among the cities of the well developed and developing countries, it is possible to create urban surroundings resistant to earthquakes by comprehensive mitigation activities. Turkish Government has decided to perform many urban transformation projects in Istanbul in order prevent future seismic damages. However these projects have been started without detailed design and analysis. The aim of this study is to analysis performance of urban transformation projects in Istanbul. The feedbacks are collected from the sides of urban transformation projects such as landowners, constructors, officials, non governal organizations (NGO). Especially Fikirtepe Urban Transformation Projects are analyzed with details. Based on studies on site and later analysis, the performances of urban transformation projects in Istanbul are evaluated.
