Evaluation of Experimental Results of GFRP-Confined Concrete and Existing Stress-Strain Models
Bibliographic record
Abstract
This study investigates the enhancement of mechanical properties in glass fiberreinforced polymer (GFRP) concrete confined with fiber reinforced polymer (FRP).Experimental tests were conducted on confined circular concrete samples with varying strengths and glass fiber contents.The axial compression behavior was analyzed by examining the stress-strain (𝜎-ε) relationship.Due to the wide range of predictive models available, selecting an accurate expression to represent the (𝜎-ε) behavior for validating experimental results is challenging.To address this, six numerical programs were developed based on six behavioral models from previous research deemed effective.These models were compared against experimental data from samples differing in strength, fiber content, and number of confinement layers.The findings emphasize the relevance and accuracy of certain tested formulations.However, some models, despite their strong research background, tend to either underestimate or overestimate the compression response, limiting their reliability for design and prediction purposes.

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.
