A continuum-based strength criterion for masonry: identification of parameters and validation
Bibliographic record
Abstract
This paper is focused on the formulation and verification of an anisotropic continuum-based strength criterion for structural masonry. In the approach followed here, the failure function incorporates a scalar anisotropy parameter whose value depends on the orientation of the principal stress system in relation to preferred material directions. An explicit identification procedure for the material parameters/functions is developed and a numerical study, including a set of simulations of biaxial compression-tension tests for different orientations of bed joints, is conducted to verify the predictive abilities of this criterion. The results are compared with the experimental data of Page (1983). In the last part, 3D finite element analysis of a shaking table test is performed involving reduced scale model of a four storey masonry building subjected to seismic excitation. A linear dynamic analysis is carried out and the plastic admissibility of the resulting stress field is assessed.

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.
