Abstract

fetched live from OpenAlex

Wood beam-columns are mostly subjected to three-dimensional load effects, such as combined compressive load and biaxial bending moment. Without appropriate provision of lateral bracings, they are susceptible to buckling in weak axis. Many research activities have been conducted to investigate the stability capacity of wood beam-columns under eccentric compression load. However, most of these research were restricted to two-dimensional problems due to the modeling or experimental difficulties. Song presented a numerical analysis procedure based on Column Deflection Curve (CDC) method and considered the biaxial bending moment. However, the CDC method can not trace the post-buckling behavior. This paper presents a Finite Element Method (FEM) based three-dimensional analysis to study the stability capacity of wood beam column subjected to compressive load and biaxial bending moments. The model considers the material nonlinearity, geometrical changes and variation of wood mechanical properties applicable to wood beam-columns with various boundary conditions. The Arc-length and Newton Raphson methods are incorporated to trace the post-buckling behavior. Parallel-to-grain wood compression and tension test and biaxial eccentric compression test of wood beam-columns were conducted to provide input data and verification for the FEM model from the perspective of stability performance.

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.
