Evaluation of rapid screening parameters and suggestions for urban transformation of reinforced concrete buildings

Recent earthquakes have shown that urban transformation has become a necessity for many cities in Turkey to achieve livable conditions and to ensure the safety of life and property of the citizens. In order to fulfill the need for urban transformation in the country, "General Directorate of Infrastructure and Urban Transformation Services" has been established under the Ministry of Environment, Urbanization and Climate Change since 2013, and building-based and area-based urban transformation has been carried out. activities are coordinated by this institution. Within the framework of area-based Urban Transformation planning, areas with high-risk buildings in terms of earthquake hazard are determined by using the First Stage Evaluation Method included in the annex of the Law No. 6306 Enforcement Regulation. It was observed that the method was insufficient to determine the risk situations of buildings and was not very compatible with the detailed analysis results. In this study, new parameters to be used in addition to the parameters used for the "First Stage Evaluation Method" were studied and it was aimed to determine the risk situation in the determined region more appropriately. In this context, 402 buildings, whose risk status was determined by static analyses from the database of the Ministry of Environment, Urbanization and Climate Change, were used. To achieve this, the parameters that may cause the buildings that are determined to be risky to be risky are determined in the database and the contributions of these determined parameters to the risky of the building are ranked from the most effective to the least using the following methods: SPSS statistical analysis software. In addition, the parameters used in the "First Stage Evaluation Method" were interpreted.
