Influence of the Design Parameters on the Current Seismic Design Approach for Automated Rack Supported Warehouses
Bibliographic record
Abstract
Automated Rack Supported Warehouses (ARSWs) are huge steel buildings offering storage solutions.These constructions have been facing a huge diffusion in the last decade, mainly due to the necessity of having bigger places to stock goods and handling them through automated systems.They constitute the upgrade of traditional steel racks, with the considerable difference of racks being the primary structural system of the building, besides being the storage place for goods.The fast evolving of the market and request of an efficient management of high volumes of goods brought a rapid development and use of such structures without their design being supported by a specific regulatory framework.This gap also involves seismic design, and this is evident from the recent collapses and damaging of such structures after seismic events.The current design of ARSWs is made adopting the same regulations for steel racks, but, even if traditional steel racks and ARSWs have several common aspects, there are relevant differences that do not allow to adopt the very same design approach.With the aim of highlighting the factors and parameters currently influencing the design of these constructions, the present paper analyses the technical guidelines and regulations currently adopted by technicians and designers, highlighting the key parameters and their influence on the definition of the seismic demand.This critical analysis is made taking into consideration typical structural configurations for ARSWs.

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.
