Overview

Randomized trial evaluates design spectrum adequacy in Tehran, suggesting improved seismic strategies.

Key Points

  • This study evaluates the adequacy of the IR-2800 design spectrum for Tehran's seismic safety.
  • Comparative analysis of IR-2800 design spectrum with PSHA-derived site-specific spectra at three locations
  • Locations include a far-fault site in the city center and two near-fault sites in the northern region
  • Development of two web-based applications, SearchQuake and HazQuake, to enhance seismic hazard analysis
  • Far-fault site shows lower seismic demand compared to near-fault sites
  • Near-fault locations demonstrate significantly higher seismic hazard
  • Findings suggest the need for revised design strategies or additional safety margins
