  • A risk–based system for managing the retrofitting of school buildings in seismic prone areas: a case study from Iran

    Earthquake events are inevitable but the consequences of earthquake disasters are partially controllable using an effective risk management system. A systematic risk–based method is proposed for assessing the resilience capacities of school buildings exposed to varying levels of seismic risk. This approach screens and monitors the equivalent seismic performance of buildings by the means of new ...

  • Linking infrastructure resilience to response requirements: the New Madrid Seismic Zone case

    Catastrophic events generate cascading and synergistic infrastructure failures that will produce unanticipated response requirements. Infrastructure failures not only influence the demands for services and commodities but also the mobility and capability of response organisations.
