Axial and shear behavior of profiled steel sheet dry board (PSSDB) composite walling system
Bibliographic record
Abstract
This research describes the structural behavior of profiled steel sheet dry board (PSSDB) composite wall panels under shear and axial loading based on experimental, theoretical and finite element (FE) analyses. The proposed PSSDB walling system consists of an individual profiled steel sheet (PSS) assembled with a single or double plywood dry board (DB) with or without concrete in-fill. The influences of various parameters such as presence or absence of concrete-infill/opening and boundary frame as well as DB-PSS/DB-PSS-DB/PSSDB-frame connections/fasteners and panel geometric/material properties on load-deformation response, ultimate load capacity and failure modes are investigated. Experimental results of PSSDB wall panels were used to validate the performance of FE and theoretical models for predicting the shear and axial strength capacity. The FE analysis coupled with experimental and theoretical analyses provides a better understanding of the structural performance of PSSDB walls and hence, helps to develop design guidelines for their use as structural units in buildings.

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.
