Pandeo crítico de vigas esbeltas con rigidizadores tipo delta diseñadas con AASHTO sometidas a cargas concentradas
Bibliographic record
Abstract
En la actualidad existen diferentes opciones para incrementar la resistencia última de vigas esbeltas sujetas a cargas concentradas. Algunas de estas alternativas incluyen el uso de rigidizadores transversales cercanamente espaciados y la utilización de rigidizadores longitudinales. Sin embargo, estudios recientes han demostrado que la resistencia también mejora mediante el uso de rigidizadores tipo delta, los cuales consisten en dos láminas soldadas entre alma de la viga y la aleta cargada. Este trabajo se enfoca en el estudio del comportamiento de pandeo elástico de vigas esbeltas diseñadas con normas AASHTO con rigidizadores tipo delta sometidas a carga concentrada. El estudio se realiza a través del análisis de autovalores usando el método de elementos finitos. Se realiza un análisis paramétrico para determinar la influencia de diferentes variables geométricas sobre el coeficiente de pandeo de la viga. Finalmente, a partir de los resultados obtenidos se sugieren algunas recomendaciones de diseño.

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.
