Reevaluating the Modified Shear Provision of CAN/CSA S806-12 for Concrete Beams Reinforced with FRP Stirrups
Bibliographic record
Abstract
The corrosion related problems does not concern only longitudinal reinforcement but also transverse reinforcement. Thus, the FRP stirrups are used as an alternative reinforcement for concrete beams. Shear design of concrete beams is a main issue. The Canadian Standards Association CSA S806 (2012) proposed shear design provision for the case of beams reinforced with FRP bars (fiber reinforced polymer). In this paper, modified provision proposed by Deifalla et al. (2014) was introduced. The aim of this study is to validate this provision in comparison with the original CSA-S806 (2012) using experimental database exist in this field. The experimental database compiled a total of 123 concrete beams with FRP stirrups tested under shear. Both the modified and CSA-S806 (2012) design provision were calculated and compared with that measured during testing. From the results, the proposed modification provides more accurate and better performance compared to that of the CSA-S806 (2012) provision.

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.
