Seismic Risk Analysis of Industrial Concrete Structures: A Case Study of an Old Reinforced Concrete Building with Shear Wall

Iran's industrial growth in the ۱۹۶۰s and ۱۹۷۰s was accompanied by the development of industrial facilities that often lacked comprehensive seismic codes at that time. This study presents a seismic risk analysis for a two-story concrete building with shear wall that constructed during this period. Seismic hazard analysis was conducted using both probabilistic and deterministic approaches, employing spectral models and validated attenuation relationships. Subsequently, vulnerability assessment, debris volume, and potential casualties from earthquakes at various intensity levels were determined using fragility curves based on the HAZUS methodology. The results indicate that during severe earthquakes, the probability of damage is very high, with debris volume ranging from ۸ to ۱۱۸ tons, although this debris would not block surrounding pathways. Casualty estimates for different earthquakes vary from less than one to ۸ fatalities. While this building is weaker compared to contemporary structures, it demonstrates acceptable performance. This study highlights the importance of considering seismic risk and post-earthquake crisis management in old industrial buildings.
