“…height and structural system) affect the building responses, which are translated into the loss through the process of the risk assessment. Safiey et al broached the necessity of rethinking irreparability models for building-specific risk assessment frameworks (Safiey et al, 2019). The significance of irreparability assessment along with limitations of the available models motivated the authors to work out a more versatile approach to modeling the irreparability tailored for the building-specific loss estimation frameworks.…”

Advanced performance-based earthquake engineering (PBEE), as documented by FEMA P-58 provisions, can well serve as the bedrock for a building-specific risk assessment framework. The methodology embraces three main sequential steps: collapse assessment, irreparability assessment, and component-wise loss estimation. The consequence of collapse or irreparability is typically assumed to be the total replacement value of the building. The irreparability model adopted by FEMA P-58 uses the residual drift of the building as the sole predictor. This article proposes a new irreparability prediction model tailored for the PBEE that is distinct because of two main features: (1) the monetary loss as a performance metric is chosen to inform the irreparability, enabling incorporation with the influence of different contributing factors, and (2) irreparability assessment is decoupled from the main body of the loss assessment and included as the post-loss analysis decision-making. Eventually, the proposed irreparability model called “post-loss analysis irreparability model (PLAIM)” is demonstrated through an illustrative example of a four-story wood light-frame building.
