A framework for the rapid assessment of seismic upgrade viability using performance-based earthquake engineering

The performance-based earthquake engineering (PBEE) methodology allows designers to deaggregate expected seismic losses in a building component level. This deaggregated information provides the opportunity tailor upgrade strategies individual structures based on sources of losses. However, optimization an strategy becomes difficult because relationship between structure and its nonstructural components; hence, multiple competing options must be considered. To address this obstacle, article proposes framework guide assessment viability both structural strategies, while accounting for limited design resources likely encountered early stages process. utilizes median shift probability (MSP) method, modified version PBEE method introduced article, rapidly summarize effects upgrades components by considering impacts modifications floor hazards. While relationship, MSP deaggregation loss across different source categories identify benefit combined upgrades, increasing designer’s understanding impact allowing rapid determination optimized unique owner’s conditions. A case study example implementation is provided, results obtained from are compared with those more rigorous but resource-intensive analysis. An Microsoft Excel provided article.
