Risk analysis of existing structures with rapid screening method

Turkey has historically been exposed to devastating earthquakes due to its location on active fault lines. Denizli, with its significant seismic potential and active fault systems, is among the regions with the highest earthquake risk. This necessitates a comprehensive assessment of the seismic resilience of the existing building stock and the implementation of appropriate mitigation measures. This study aims to evaluate the seismic safety of the existing building stock and identify potential risks. The assessment considers critical parameters such as building age, number of stories, short columns, soft stories, cantilever projections, visible construction quality, and the pounding effect. A scoring matrix has been developed based on rapid assessment methods available in the literature, and the buildings within the study area have been evaluated accordingly. This approach enables an objective classification of buildings based on their seismic vulnerability, ranking them from the highest to the lowest risk category. Consequently, it facilitates the identification of priority areas for earthquake mitigation efforts. The data obtained from field investigations have been analyzed within this framework, providing a comprehensive evaluation of the seismic resilience of buildings in the region. In conclusion, this study assesses the overall condition of the regional building stock and proposes a roadmap for earthquake-resistant urban planning through a prioritization-based approach. Moreover, by demonstrating the practical applicability of rapid assessment methodologies, it provides a scientific foundation for local earthquake preparedness and risk mitigation strategies.
