From: Strengthening of Cutouts in Existing One-Way Spanning R. C. Flat Slabs Using CFRP Sheets
Model | CFRP sheets configuration around cutout | Ultimate load (kN) | % increase ultimate load |
|---|---|---|---|
S1 | – | 55.2 | – |
S3 | Parallel to cutout edges | 60.0 | 8.7 |
Inclined 45° at cutout corners | 57.0 | 3.2 | |
S4 | Parallel to cutout edges | 45.8 | 9.0 |
Inclined 45° at cutout corners | 43.4 | 3.3 |
