Abstract
<p>The UCSF Health Hellen Diller Hospital is a new 15 storey hospital planned in San Francisco. The lateral system is a Special Moment Resisting Frame (SMRF) with supplemental viscous damping. This unique lateral force resisting system created a difficult connection detail in connecting the high precision pin connections of the dampers and braces in the damping system with the structural steel of the moment frame. The project’s design team determined that custom designed cast steel brackets would provide the most economical means of connecting the damping system to the SMRF connections, while also improving constructability. This paper introduces the bracket designs and provides context on the project. The method defining optimal bracket groupings based on geometry and loading requirements is presented. General design approach, including non-linear finite element analysis, and topology optimization of the bracket designs to minimize their weight is presented in detail.</p>

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
