Urban transformation applications in Istanbul: Example of Bahcelievler urban transformation

In this thesis, under the title of 'Urban Transformation Applications in Istanbul, the subject of Urban Transformation is discussed with all details, Urban transformation projects implemented in our country, legal dimensions, in terms of urban transformation in our country and especially with the earthquake risk details of Istanbul, the all problems and sample applications are emphasized. Also within the scope of the thesis, all technical analyzes to be done in the process of urban transformation and the approach and applications of the Ministry of Environment and Urbanization to the subject were discussed. In the study, an exemplary structure within the scope of the urban transformation project in the Kocasinan neighborhood of Bahçelievler was investigated in detail in terms of Geophysical Engineering (Soil-Structure and Earthquake) and Civil Engineering (Geotechnical and Structural). Within the scope of the thesis, the geology and soil characteristics of the construction area were defined, and the necessary laboratory experiments and analyzes were carried out by the Ministry of Environment and Urbanization in order to enable the project to be included within the scope of urban transformation. In this study where urban transformation applications are evaluated, negativities in the structure, element details in the existing structure, destructive and non-destructive methods were found, corrosion rates in the elements were calculated and the reinforcement ratios and material properties were examined in detail and the concrete strength of the existing structure was determined. In the scope of the study, standard penetration tests from the drilling wells were gathered for field surveys of the project area and undisturbed UD samples taken by Shelby tube were investigated. In order to determine the dynamic and elastic parameters, MASW (Multi Channel Analysis of Surface Wave) method was applied. Performance analysis was applied with the help of Sta4cad program in accordance with the Law No: 6306 on the Transformation Areas Under Disaster Risk.
