Abstract

fetched live from OpenAlex

Tall buildings become increasingly sensitive to wind as they go higher and for super-tall towers, which are going up at an increasing rate, wind becomes the dominant factor in the structural design, not only for strength but also for keeping the building motions within a comfort range for the occupants. Along wind forces are important but even more important are the crosswind forces. While stiffening the structure, increasing its mass, or adding supplementary damping systems are all ways of reducing the response, it must be remembered that the source of the wind excitation is interaction of the wind with the building's shape. The dominant form of excitation of building motions is often vortex shedding. Various shaping strategies such as tapering, varying the cross-section with height, softening the corners, using spoilers, and inserting openings in the building have been used to mitigate or even completely suppress vortex excitation. The alignment of the tower with strong wind directions or even with other towers nearby can also be important. Substantial cost savings are possible if the effect of shape is taken into account early in the design.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
