Abstract
The innovative combination of prestressed carbon fibre reinforced plastic (CFRP) wires and high performance concrete (HPC) opens up promising possibilities in the design of structural elements and load-bearing structures. This enables manufacturing of thin-walled, lightweight, filigree, fatigue resistant and very durable concrete elements with very low raw-material consumption for use in several market niches of the construction industry. Two or more of these advantages should simultaneously apply to the intended application for justifying the higher material costs of prestressing and passive CFRP reinforcements in comparison to prestressing and reinforcing steel. Significant economic benefits are to be found in the areas of maintenance of the load-bearing elements as well as their transport and installation. Recently, a first commercial breakthrough of this novel technique was achieved in the structural and architectural field with the realisation of two large building façades in Zurich, Switzerland using a total of 3000 m prestressed self compacting concrete profiles. In this paper design and experimental validation details as well as several field projects are described.

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 it
