Especially, the large-scale loss of life and property caused by the significant earthquakes in recent years has brought the importance of research and measures to be taken on this issue. Determining and analysing the ever-increasing building stock of the cities and detecting and managing all information related to buildings are important in terms of spatial planning and urban transformation. This study aims to determine tectonic characteristics calculating a and b values of Gutenberg- Richter magnitude-frequency relation which forms the basis of earthquake statistics for all cities in Turkey and the reinforced-concrete buildings which are primarily risky in terms of urban transformation. For this purpose, a total of 1620, 5-storey buildings from all provinces of Turkey were assessed. Twenty reinforced concrete buildings from each province were taken into consideration which has 5-stories. The first stage evaluation method specified in the principles regarding the identification of risky buildings issued in 2013 by the Republic of Turkey, Ministry of Environment and Urbanization was used in this study. The performance scores for 1620 buildings were calculated by using this method. A risk priority map was created for the provinces, taking into account for these buildings. The study aims to determine risk priorities of site and mid-rise reinforced-concrete buildings among the cities. The results obtained were interpreted and recommendations were made.
