Özet
This paper aims to determine the seismic risk distribution of old masonry buildings located in Galata, the historical region of istanbul. In order to obtain seismic risk prioritization of the built environment, the seismic vulnerability assessment of 40 old masonry buildings was carried out according to both the Vulnerability Index Method (VIM) based on the European Macroseismic Scale (EMS-98) and the procedure in the Specifications for Determination of Seismically Vulnerable Buildings (SDSVB 2019). In the first part of the study, using the building data gathered by the screening process on site, the vulnerability scores (VS) comprising the structural and non-structural parameters were obtained and the performance score (PS) of each building was calculated according to SDSVB 2019. Depending on the results, in order to determine the seismic priority levels, the buildings were ranked from the lowest to the highest performance score and classified in terms of their structural vulnerability. Then, in the second part of the study, the vulnerability index (VI) for each building was determined depending on the building parameters affecting the structural vulnerabilities. On the basis of vulnerability indexes, damage grades of the buildings were estimated, and accordingly, the damage distribution was acquired for the building stock. Additionally, the seismic risk distribution maps were compiled for the building inventory according to the findings achieved from both methodologies. As a result of this study, the differences between the two first-level procedures were outlined with a comparative assessment, thereby demonstrating the importance of seismic risk prioritization of the historic built environment for city-scale risk management strategies. © 2022 Published by ISRES Publishing.
