Risk-Based Seismic Retrofit Prioritization of Reinforced Concrete Civic Infrastructure: Case Study for State of Oregon Schools and Emergency Facilities

Abstract

The state of Oregon is in a high seismic hazard zone, which raises serious concerns for potential damage, even collapse, of older concrete schools buildings and emergency facilities. In order to allocate retrofit prioritization funds, a risk-based evaluation is performed for over 600 of Oregon’s civic reinforced-concrete buildings. This risk-based seismic retrofit prioritization can be used by Oregon’s newly established seismic rehabilitation program to highlight those buildings needing further detailed evaluation and mitigation to minimize casualties and increase community preparedness. The risk-based prioritization can also be applied to structures in other high seismic regions.
