Abstract

fetched live from OpenAlex

The large deflection behavior of a uniaxially bent beam-column subject to an eccentrically applied load is investigated. A closed-form expression for the total lateral deflection, including bowing and initial imperfection, is derived by adopting a nonlinear strain-displacement relationship and a sine curve approximation for the lateral deflection. Stability is checked by evaluating the Hessian matrix of the total potential energy. The formulation is validated by applying it to a steel beam-column with an L/r ratio of 200. Though not comprehensive, results indicate that it is possible to develop reasonable closed-form solutions for the nonlinear behavior of slender beam-columns.

Full frame distilled prediction

Teacher imitation

Not 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.
