The effect of traffic vibration on adhesive curing during installation of bonded external reinforcement
Bibliographic record
Abstract
This paper describes a programme of research which was conducted to examine the effect of traffic vibration on adhesive curing during the installation of bonded external reinforcement. Steel and carbon fibre reinforced plastic (CFRP) plates were used in conjunction with four epoxy adhesives. A literature review was undertaken in order to select appropriate magnitudes for the strains and frequency of vibration to be used during an experimental programme involving the vibration during cure of lap joints, steel and reinforced concrete beams. The lap joint results show that vibration during cure causes a progressive reduction in strength with increasing strain level. The tests involving strengthened steel beam specimens suggest that use of simple lap joints will give a safe prediction of the effect of vibration during cure. In the reinforced concrete beams there were noticeable differences in failure mechanism between those strengthened with steel as opposed to CFRP plates. However, in both cases failure modes in the concrete masked any effect arising from vibration during cure. Recommendations for the design of externally reinforced concrete elements have been proposed which involve increasing the partial safety factor on the ultimate shear strength of the bonded joint if the joint is to be subject to traffic vibration during cure.

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.
