Implication
Beam tests reveal bond behavior and strain measurements in CFRP prestressing, highlighting implications for structural integrity.
Key Points
- CFRP prestressing led to significant observations of splitting cracks, impacting beam performance.
- Maximum prestress force was calculated using DFOS, indicating critical thresholds for cracking.
- The study employed a Thick-Walled Cylinder Model, aligning closely with DFOS data on circumferential strain.
- DFOS proved effective in monitoring internal crack progression, emphasizing its role in assessing concrete structures.
