SEISMIC HAZARD MITIGATION DECISIONS USING PBEE:FINANCIAL METRICS AND A CASE STUDY

摘要

We explore the analysis and communication of seismic investment decision variables to corporatedecision makers and investors within the Performance Based Earthquake Engineering (PBEE) framework.One approach in facilitating the communication between the corporate clients and PBEE practitioners isbased on making tradeoffs between several alternative levels of mitigation: status quo,moderate/extensive retrofit. Annual exceedance probability curves are obtained from the PBEEframework for three hazard dimensions most frequently demanded by decision makers: number offatalities, downtime, and structural loss. The level of mitigation and the reduction in structural losses aremodeled and simulated using several financial decision-making criteria.
