Pre - and post-cracking behaviour of fibre reinforced concrete beams on grade
Bibliographic record
Abstract
Structural design of strip, combined footings, and raft foundations is commonly based on an elastic subgrade assumption. The subgrade is either assumed to be a continuum or to consist of a series of discrete springs and the foundation is assumed to behave elastically. Experimental verification of the simple case of elastic beam on subgrade reaction is reported in the literature, but the data are not extensive. Furthermore, the data pertaining to concrete beams on elastic subgrade before and after cracking is almost non-existent. Therefore, an experimental program was undertaken to study pre- and post-cracking behaviour of steel fibre reinforced concrete beams on elastic subgrade. Two types of subgrade and different end boundary conditions were studied. The beams were subjected to a concentrated point load at the centre. The results of the experimental program are compared with predictions assuming soil to be represented by a series of discrete elastic springs. The results of this study will also help in developing a better understanding of the soil-structure interaction of fibre reinforced concrete slabs on grade, which are being increasingly used in industrial warehouses.

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.
