Abstract
Tall buildings with different structural systems can be exposed to explosive loading, and a proper understanding of their structural response under blast loads is crucial for robust structural design. This study investigates the structural performance of selected tall structural systems - shear wall frame, outrigger, and tube-in-tube systems - under different blast load effects. Nonlinear finite element analysis was performed using commercial package ETABS with blast loads applied as time-history functions for various charge weights and standoff distances. Structural responses were compared in terms of displacement and inter-story drift. Results showed that the tube-in-tube system performed relatively better in terms of displacement and inter-story drift as standoff distance increased and charge weight was constant. When explosive charge weights increased, and standoff distance was constant, the tube-in-tube system displayed better performance with respect to displacement, whereas the outrigger system was the optimum with reference to inter-story drift. The overall study indicates that selecting a tall structural system for better resilience against blast loading depends on specific aspects of structural behavior, identified as the required criteria.

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
