Abstract
It is widely recognized that high-seismic regions across the world are frequently affected by repeated earthquakes. The destructive effects of repeated earthquakes have been investigated by many researchers using performance parameters such as residual displacement, inter-story drift, and dissipated energy. In this study, a high-rise reinforced concrete shear wall building with 40 floors above grade, which represents a typical real tall building, is selected as the example building for numerical analyses. Nonlinear response history analyses are performed under different combinations of earthquakes with various spectral acceleration intensities. The analysis results for the tall building under the earthquake sequences indicate that concrete strain governs the seismic performance level of the building, while steel strain consistently meets the immediate occupancy limit. The study concludes that the immediate occupancy threshold, defined by the concrete strain at peak stress, is a critical limit for preventing significant damage under repeated seismic demands.

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 it
