Critical Evaluation of Design Methods for Overhanging Steel Girders
Bibliographic record
Abstract
This paper assesses existing design procedures used to determine the flexural resistance of overhanging steel girders as part of the Gerber roof framing system. Three design procedures are first introduced for overhanging girders based on the available design methods for their individual segments. A data set of nonlinear finite-element analysis results consisting of 7,539 practical overhanging steel girders is then developed. Three different loading and lateral restraint conditions at the cantilever tip are considered: (1) loaded at the shear-center level and unrestrained; (2) loaded and restrained at the top-flange level; and (3) loaded at the top-flange level and restrained at both the top and bottom flanges. All the point loads and lateral restraints at the back span are provided to the top flange at joist-to-girder connections. The results of the numerical simulation are used to critically evaluate the three design procedures and make recommendations regarding the conditions under which each design procedure may be overly conservative or unconservative.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
