Abstract

Seismic vulnerability and risk assessments constitute a key component of disaster risk reduction strategies aimed at minimizing casualties and economic losses. The accuracy and reliability of these assessments depend on post-earthquake damage data, which provides valuable insights into the performance of structures during earthquakes. This study focuses on single-story precast RC industrial buildings that were damaged during the Mw 7.7 and Mw 7.6 Kahramanmaraş earthquakes on 6 February 2023. Common types of structural damage were identified through detailed on-site inspections of the affected buildings. Subsequently, analytically-based fragility curves were developed for a representative, typical single-story precast RC building model using different intensity measure parameters. In the final part of the study, the influence of various intensity measure parameters on seismic loss estimation was evaluated comparatively by calculating Probable Maximum Loss (PML) values through the integration of fragility curves and damage-to-loss functions.
