Special issue: 2010 los angeles tall buildings structural design council—2010 magnitude 8·8 chile earthquake
Bibliographic record
Abstract
Abstract It is a pleasure to present the seventh annual issue developed by the Los Angeles Tall Buildings Structural Design Council. This two part issue is devoted to the Offshore Maule earthquake that shook Central Chile earlier this year. These two issues represent significant lessons learned from this earthquake. This earthquake is very significant as it presents a unique opportunity to study the effects of a true mega earthquake (with moment magnitude of 8·8) on modern tall buildings designed with contemporary building codes and constructed with modern construction methods. The building codes and construction methods are similar to those used in the USA so this event should be of interest to all structural engineers. This earthquake occurred on the South American subduction zone, which has uncanny similarities to other similar subduction zones around the world including the Cascadia subduction zone off the coast of the Pacific Northwest of the USA and Southern British Columbia, Canada; other subduction zones include those off of Alaska, Japan, Philippines and Indonesia. Thus, this earthquake gives us the first opportunity to develop an understanding of the behaviour of tall buildings to subduction zone events. Copyright © 2010 John Wiley & Sons, Ltd.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
