A Methodology to Leverage Seismic Risk Assessments to Inform Seismic Policy Development, the Case of the City of Vancouver

National Conference on Earthquake Engineering (12th : 2022 : Salt Lake City (Utah))

Seismic risk reduction planning for existing buildings must begin with a quantitative account of risk, and it must contain an objective basis grounding the various policy options considered within it. This work proposes one methodology for generating that objective policy basis, leveraging seismic risk modelling outputs to detail the benefits of various policy options to reduce risk in Vancouver’s 90,000 existing, privately held buildings. This methodology considers risk in terms of casualties, building damage, disrupted occupants, and direct financial losses, creating a process to model the reduction across each risk metric for cohorts of buildings. These cohorts are ranked by their impact upon the desired metrics, allowing for identification of efficient policy strategies from a test set. In effect, it allows municipal staff and decision makers to understand the potential for risk reduction and make informed policy decisions, including risk reduction targets, to advance citywide seismic resilience.
