WITHDRAWN Geophysical Case Studies of Buildings in Tehran Against Earthquakes

Description: 

WITHDRAWN Earthquakes are natural phenomena that occur annually in various parts of the world, leading to significant human and financial losses. Since earthquake engineering cannot precisely predict the time, location, or intensity of earthquakes, one of the primary strategies to mitigate earthquake damages is proactive preparation and the identification of vulnerable structures. Structural retrofitting efforts, based on scientific and technical solutions, are essential for urban development, though the approaches vary across regions. Iran, situated within the seismically active Alpine-Himalayan belt at the collision boundary of the Eurasian and Arabian plates, is highly prone to earthquakes.This research investigates the seismic vulnerability of government buildings in Tehran using geophysical assessments. For each seismic vulnerability evaluation method, specific criteria were selected based on their importance and drawn from previous validated studies. The data collected were analyzed using analytical and descriptive methods, with tools such as MATLAB, GMT, Saizen, statistical programs, and Excel.The findings confirm that probabilistic seismic risk assessment maps are highly effective as predictive tools. The satisfactory alignment of conventional results with those obtained through the newly processed method indicates the reliability of this approach. The research demonstrates that real-time probabilistic seismic hazard assessments can be achieved, with updates incorporating the probability of seismic sources within shorter temporal and spatial intervals. These updated assessments are highly valuable for risk analysis processes. Future research can enhance these models by incorporating smaller time frames for seismic source probabilities, improving both the robustness and accuracy of earthquake,occurrence predictions.
