Assessment of Disaster Resilience Performance of Structural Systems in relation to Design Response Spectrum
Bibliographic record
Abstract
The system-reliability-based resilience analysis facilitates the investigation of the joint capability of structural components to resist system failures. This approach has recently been extended to evaluate the resilience of structures subjected to stochastic excitations, such as earthquakes, based on the concept of reliability and redundancy curves. The reliability and redundancy curves are evaluated in a manner similar to traditional seismic fragility curves and are, therefore, capable of capturing the site-to-site variability of hazard characteristics, such as frequency content and duration. To quantitatively examine these aspects, the present study conducts a comparative analysis of two structures with identical designs but located at two different sites: Gyeongju, Korea, and Vancouver, Canada. The excitation properties at the two sites, which exhibit different frequency characteristics, are described using site-specific design response spectrum curves. Subsequently, a set of ground motion acceleration time histories is generated using a spectrum-compatible ground motion modeling approach. The generated ground motion sets for each site are applied to a 6-story frame structure, and a resilience analysis is performed. The numerical study demonstrates that the system-reliability based resilience analysis successfully captures site-specific characteristics and that these characteristics can significantly influence resilience evaluation results.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
