A case study on the updates of Turkish rapid visual screening methods for reinforced-concrete buildings

Abstract

The changes in rapid seismic assessment methods that can be used to determine the regional earthquake risk distribution of buildings have become inevitable, with the Turkish Building Earthquake Code and Turkish Earthquake Hazard Map which updated in 2018, Within the scope of this study, risk prioritization was made according to the last two regulations for ten different settlements that located in the same earthquake zone in the previous earthquake map. With the current regulation, it has once again emerged that site-specific based analysis and evaluations are necessary. While the building performance scores in the previous regulation were the same for all provinces since they were located in the same earthquake zone, different values were obtained for the provinces with the current regulation. As the PGA value increased, the design spectral acceleration coefficient increased and the building's performance score was lower. This increases the risk in these regions.
