Developing a gis based application for determining regional earthquake risk distribution using simplified methods according to ryteie 2019

Turkey, which is located in an active earthquake zone, is a country that has been severely injured by earthquakes in recent years. It is a known fact that the biggest factor in the emergence of these severe consequences is the existing building stock, which is not earthquake resistant. Accordingly, the Ministry of Environment, Urbanization and Climate Change has made it mandatory for the relevant administrations to prepare Urban Transformation Strategy Documents in order to manage the urban transformation process in a holistic manner. Within the scope of the preparation of the Urban Transformation Strategy Document, conducting existing building stock inventory studies is of great importance, especially in terms of civil engineering. There is a need to identify risky buildings on a building basis, determine the regional earthquake risk distribution of buildings and prioritize the work. Instead of dealing with documents such as printed forms, photographs, etc., the personnel who will scan the buildings should be able to digitally enter the information for the buildings with predefined spatial data, thus accelerating the data collection studies and accelerating the preparation of the Urban Transformation Strategy Document. In this thesis, the conceptual model of the software needed to determine the regional earthquake risk distribution and prioritization studies by using simplified methods in line with the Principles Regarding the Determination of Risky Buildings within the scope of Law No. 6306 on the Transformation of Areas Under Disaster Risk was determined and Geographic Information System Based Building Stock Inventory software specific to this study was developed. It is thought that this software will facilitate the building stock inventory, which is especially needed by metropolitan municipalities, and the calculation, classification and reporting of building and regional performance scores with rapid evaluation methods. Considering the results of the study applied in Eskişehir, it was concluded that the developed software can be used by all local governments.
