Abstract
Members subjected to both axial and transverse loads are called beam columns. The beam columns containing different supports and loading including continuous beam columns are analyzed for buckling. Both primary and secondary bending moments are considered. The differential equations of second and fourth order are used to solve different cases of loading and support conditions. Infinite series for trigonometric functions and binomial theorem are applied to find maximum deflections and bending moments. The slope deflection equations are derived for beam columns and the slope deflection coefficients for beam columns are given in the Appendix A. Elastic and inelastic analyses are performed on beam columns to draw the slenderness ratio versus critical stress graphs known as column strength curves. The American Institute of Steel Construction (AISC) design criteria for steel beam columns is given for both the allowable stress design (ASD) and the load resistance factor design (LRFD). Eurocode3, Canadian Standards Association, and Australian Standards design equations are given for beam columns. The design of steel beam columns is illustrated by solving a problem in both AISC ASD and LRFD methods. There are seven practice problems and nineteen references at the end of the chapter.

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.
